 you have a copy of this. Please take out your schedule. Now, this schedule is absolutely tentative. It is for us to decide what to do at what time. So, we will move things around. Perhaps the only fixed things here are the three days, the tree breaks, the beginning time at 9 am and the closure time at 5.30 pm. Depending on our discussions, we will move the topics and discussions up and down. The one thing which is certain is that on the third day, that is on Friday, the additional topics and discussions after the lunch break are shifted to the morning session. We will reschedule cycle somewhere else, because out here, we will have a Moodle-based quiz and then the validity. So, for you to complete your registration formalities and for those who do not yet have a Moodle or have not yet logged in on Moodle, to complete the Moodle formalities, the break for T instead of 11, I will allow a break from 10.45. The T may still arrive at 11, but those 15 minutes may be used for completion of registration and completion of your Moodle logins for those who have not done it. Before we start, few questions to be answered by raising hands. How many of you were coordinators for last year's thermodynamics course? One, only one overlap, good. Where are you from? Anil Agrawal, from Jaipur Engineering College, Jaipur, Rajasthan. Jaipur Engineering College. College, Jaipur. Rajasthan. So, nice to have you back. Thank you. Was this doing, this again was by design or by accident? No, sir, for design only. Yes, any way, at least one person is common. The related question, how many of you were not coordinators, but participants in the earlier thermodynamics course? Okay, so there is a reasonable number of exposed people, but I am also happy that there is a large number of new people who have not been exposed to the thermodynamics earlier, either as coordinators or as participants. Then third question, how many of you have been either coordinators or participants in other courses which have been conducted under the NMEI CT scheme? For example, in mechanical engineering, we have conducted two more courses, one on heat transfer and one on fluid dynamics and CFD. But at the general level, we have conducted a teacher's workshop, a research methodology workshop and an Akash workshop. So, any one or more of these, how many were involved? Quite a good number. So, I think I will put it around how many have never attended or coordinated any NMEI CT one? That also is a good number. So, our catchment is slowly widening. That is a good thing. Now, let me start with a negative question. How many of you are not comfortable with the computer software called Moodle, use of Moodle? Not comfortable or have never used it? 1, 2, 3, 4, about 10, 15 percent. I am told that the quiz on the third day will be on Moodle. So, before that, at some time through the machine which is here, I will expose you generally about how that quiz will be conducted, how to login on Moodle and how to go about using Moodle. It is just if you have ever filled in a railway reservation form or an aircraft airplane, airway reservation form or any other transaction on the web, Moodle is no different. It is just a different format. It will be a question and there will be a number of options or a small text box for you to fill. Since this is the sort of a second implementation of thermodynamics, that is why I told Professor Fatah and since we are pressed for time, in IIT, Bombay also this is the semester and examination time. So, that is why you will find that we are unable to conduct this in a classroom environment. We are forced to conduct this in an auditorium type of environment because the classrooms are being used for examinations both morning and afternoon. So, we could not even find one full day for this workshop and because of this pressure and availability of space, we reduce this to three days and what I decided to do is in the those who have participated earlier would have noticed and on the NMEI site, NMEI city site the recordings are available. The coordinators workshop was a full, essentially a full lecture demonstration session over five days. Over three days if I do that, that will be doing too much in a hurry. So, what we will do is we will change this thing that we will have a discussion now about how to proceed, what to emphasize during this coordinators workshop and a set of discussions about how to manage the final workshop. There are certain subject related issues and there are certain implementation related issues and we better be very clear about it. For example, consider the first thing, last time when it was conducted, I had 34 coordinators sitting in front of me in a small room. I could almost by the second or third day, I could almost identify each one by face a few by names. You should excuse me because I have a very poor memory for faces and names. So, please identify yourself if you meet me now or later that I am so and so from this and from then we will discuss. Otherwise, I am likely to get totally confused with you know your number almost reaching crossing 150 and reaching slowly tending towards 200. Even in this session it will be difficult for me to individually talk to you in this three day work. And I am sure the questions and queries which come although I will take questions, I also have a parallel thing going on. Soon you will have with you slips like this. So, what we do in conferences, this is another possibility at any stage you have a question write down the general topic. Topic is just one or two words say first law, second law and things like that. If you want to identify your name that optional space is available for writing your name and then questions, queries, comments you write before that. In between sessions these things will be collected sorted. So, I will know which are the main queries for which I should be ready for discussion. That will save us even if it saves me 10 minutes and saves us 10 minutes per session over three days about hour, hour and a half would easily be saved. This is just a time saving measure that does not mean that if somebody raises a hand I am not going to, I am going to just neglect that. At some time I will pause and say what is the question and go ahead with it. And there will be volunteers here and one of your participants Dr. Mangesh Chaudhary has been our student here. I think you were my TA for a thermodynamics course at some time, some here. Which year was that? 2001, 12 years. But thermodynamics does not change in 10 or 12 years. But you will notice the differences the way we taught it that time and we are teaching it now. And I am also going to take his help to see this out and arrange them in topic order. Now let us get used to the packet which you have. Take it out. The first thing you should note is the form permission to use the course lecture workshop material in open source. I hope you have filled up this form during the registration process. If not you must fill this up and provide it at the registration desk. That is the first announcement. Now you will also have a schedule that is just to see to it that you get it in sharp focus. The focus here may not be that good. Then there are two more stapled bunches of paper, a thin one and a thick one. The thin one says sequence of topics. And after this was printed, there was a change of date. So the first thing you should do is change the dates 12 December to 012, 22 December to 012, to 11 December to 21 December. Because it was only day before yesterday that because of some logistic reasons and other comfort levels. We made it 11 to 21 and remember that 11 December is a Tuesday. 21 December is a Friday. So we will have Tuesday, Wednesday, Thursday, Friday, Saturday as the first five day session. Sunday will be off and then Monday, Tuesday, Wednesday, Thursday, Friday. With this we could have two five day sessions with the intervening day being Sunday which has a higher comfort level. And also the last day is a Friday followed by a two day weekend. So it is comfortable for you to travel back or go to any other place that you feel like. You will also notice that this is a draft for discussion. So as we proceed we will first thing is if by default we would like to proceed in the way this scheme is laid out in front of you and we will come to that discussion. And one of the things which we have to do during these three days is to decide which ones of these should we emphasize, which ones of these should we deemphasize. Because for this three day workshop as in the final ten day workshop the main constraint is time. Within that time we have to do justice to admins of engineering thermodynamics as possible. So this is one. The next one is it slightly thicker set. This is not a complete set. Let me make it clear. But to begin with these are the set of exercises which we will be using. And the first correction this will be made in the final versions after this workshop. Bottom line make it December 11 to 21. And when I say this is incomplete you will notice that if you compare the topics in the scheme topic 13 is introduction to cycles. On the last page we have 14, 15, 16, 17 the proposed additional topics. But the exercises pertaining to those have not yet been included here. We may include one or more of the additional topics 14 to 17 in this workshop. And I have delegated the responsibility of handling those topics if included to my two colleagues, Professors Van Darker and Purani. But because of their academic things they could not prepare a set of formal set of exercises. Whatever topics are included appropriate set of about a dozen exercises on each topic will be included in the final set of exercises. Let me also tell you that I had set out a questionnaire to participants in the previous course on thermodynamics where the structure was very similar. In fact essentially the same scheme of topics. Essentially the same set of exercises but some exercises are modified. I have in the last year and a half whatever new exercises or new problems I have set for quizzes in semester examinations they have been included in this or some of them have been included in this. So what I had done was on through Moodle for last time's main workshop I had set out a questionnaire asking for feedback. There were some 800 participants but the feedback was provided by just 40 of them till early today morning. So one thing we are going to do is look at that feedback and then start our discussion. The structure of this particular three day workshop will be like this. Looking at the feedback and after some initial discussion we will decide whether this set of topics is the proper set of topics. Emphasis we will decide as we go. The second thing is we will decide how to implement things in the final workshop. I want to discuss mainly the following. One is interaction, second one is exercises, and the third one is post workshop assignment. So the first exercise for you is to browse through this set of topics and at the end of those four or five minutes I would like to receive comments about whether this is the reasonably proper and reasonably complete set of topics which we should cover. I would specifically come to 14, 15, 16, 17 later but our first discussion would be based on the, will be regarding the first 13 topics, few minutes. I suppose we have had time for going through. So go back to the scheme of things which you teach at your place. This may be slightly different. May be in order, in our scheme of things right from 1 to 12 are taught in a course called just thermodynamics. Earlier it was called basic thermodynamics and in another course called applied thermodynamics we have 13, 14, 15, 16, 17 not 17, 13, 14, 15, 16 and some more topics. I understand that at many places the course in thermodynamics is split into two parts. One part the first half absolute basics are taught in a course called introduction to engineering or introduction to mechanical engineering. The second part which is taught only to mechanical engineers comes sometimes in the second year and may have a slightly different name. So whether it is taught in one shot or in two shot I first want to have your opinion as to whether 1 to 12 or 1 to 13 constitute a reasonably complete set of topics for thermodynamics. Yes or no? Anybody has a vehement objection to this scheme of things? Yes sir. Specifically they are not included here but when we come to first law open systems a reasonable number of unsteady professor. There is no special topic in that. If it comes up we will handle unsteady so that we will take care of as we go because there is some historical reason why we teach thermodynamics in this particular way at IIT Bombay. There is a long history of that. The origins of the history I do not know but I was an undergraduate student here between 1968 and 75 and at that time it was a 5 year program after 12th as professor Fatuk said and in the first 2 and a half to some extent 3 years there was a lot of emphasis on physics, chemistry, mathematics, humanities and engineering skills like workshop, drawing. Of course from second year onwards applied engineering courses also began like applied mechanics, materials, circuits and so on. But I was exposed to very rigorous or I should not say I we were exposed to very rigorous thermodynamics in physics as well as in chemistry before we came to mechanical engineering thermodynamics. When around 80s early 80s the 5 year program was modified to a 4 year program because of the school curriculum modification to the 10 plus 2 plus 3 for general education and 10 plus 2 plus 4 for engineering education. It so happened that the emphasis on the physics, chemistry, math in the first 2 years had to be significantly reduced. Many departments in particular mechanical engineering department then decided that this is not a good idea because we depended on a good physics background in many subjects like mechanics, wind mechanics and thermodynamics. So it was decided that whatever was done by the physics department for us, for mathematics department for us we will do internally in our course. So when I learnt thermodynamics, significant basic thermodynamics I learnt in a physics course. It was called thermodynamics but was taught by a professor of physics in my case professor Blatka. When mechanical engineering department redesigned the 4 year course it was decided that that part which was taught by a physics professor will also be taught by our own teachers. And that is why you will find that this course starts where a physics thermodynamics course starts off and then goes into applications. That is why out here we have significant emphasis on the basic principles and basic understanding of the principles of thermodynamics and basic derivations from basic understanding a derivation based on the 3 laws of thermodynamics. That is the historical reason. I agree that at different places maybe even in IITs the emphasis will be different. The emphasis is another thing but the first thing I think I am happy that we agree that the first 12 topics essentially constitute our basic engineering thermodynamics. So far as the scheme in mechanical engineering is concerned. If you go to thermodynamics as applied to chemical engineering the way chemists learn it, chemical engineers learn it. Although the absolute basic principles are the same the applications and hence the way the whole thing is derived is different. Me and my colleagues and I think most of you have a background in mechanical engineering. So we would essentially remain in the mechanical engineering scheme of things so far as thermodynamics is concerned. Now the next thing which we have to discuss and let us spend some time on this is the emphasis. I had asked the following questions to participants in the earlier workshop. So I will tell you something about the feedback which I have received so that the discussion can proceed in that manner. See I had listed out these 13 topics which were covered in the last workshop on thermodynamics and I had asked the respondents to tell me whether that topic should be deleted one option, one extreme option. Second the topic should be de-emphasized that is spend less time on it. The third one do not change the emphasis on the topic keep it as it is. And the fourth one improve the emphasis put more time and effort on that topic. So it became a 13 column 4 row or 13 row 4 column matrix, 13 by 4 matrix and that is too much of a detail. So what I have done is I have said that I have combined the de-emphasize and delete comments together and I have combined keep the emphasis the same or improve it together considering the first two as a negative sort one way, the second two as the positive sort. So if you take topic one the they say the negative part and the positive part. The negative part is 26 people, positive is 15. Topic two is 14 to 21. Topic three is 8, 23. Topic four is problem solving, problem solving, problem solving 18, 26. I would encircle something which is significantly higher than the other. Topic five first law 9, 22. Topic six, zero law, temperature 12, 18. Topic seven, thermometer equations of states, properties of steam, 2020, no variation. Eight properties of fluids, steam tables, etcetera, 21, 19, again no significant change. Then second law 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20 was 10, 27. Property relations, 9, 27, 11 was open systems, 16, 17, 12. Combine first and second law, this is availability exergy and 17, 27. C disastrously offering Batcubин So, if you look at it only the first topics introduction and the last topic cycles, the comment was that look you may spend less time on it, whereas for all others they said keep the emphasis as it is or increase the emphasis. So, that is just the background and mind you this is a very small sample of just 40 people who were participants in the earlier one, that is history just gives a hint of what they thought processes perhaps where, but remember 40 out of 800 is again just 5 percent, small sample. And this is a new edition, this is a new set of people in the new set of participants much larger than 800 definitely. So, it is for us to decide over the 3 days how to allocate time in the main workshop, not in this workshop. In this workshop as professor Kulkarni said there are certain issues which you have not for many of you may not even have heard some nomenclature, some name, some terminology well it is my job to explain that completely. So shall I say that considering this at least to begin with let us go through the whole scheme of things and then we can decide what to do and whether to significantly reduce something or significantly increase the emphasis on something, but one thing I think I would recommend and I think all of you agree that in some way or the other all these things needs to be covered or uncovered during a course in Tamil Nadu. Yeah that is why I did not tell you the deletion, see there is a paucity of time, so although deletion is out of question because that would break the whole thing apart. Reducing time provided for a certain topic is something we may have to do because finally it is 10 days into 6 or 6 and a half hours a day, it is about 60-65 hours and sometime we will go in interactions. Now that brings me to another topic, so let me if I have brought it up, let me bring again it to the floor. Last time we had finally 31 centers for Tamil Nadu, each center typically had anywhere between 15 to 40 or 50 participants, the total participants I think was 840 or something. Because there were only 31 centers although some centers were more active in interaction, some centers were rather dormant or passive, I am sure I was able to interact with each and every center and with a reasonable amount of time. But even then that was possible when every day I provided almost the whole of the afternoon session for interaction, it started off with a problem solving session and the session started off with by saying that look we have learned so many things so far, now from the exercise sheet we are ready to tackle problems this up to this. So to start off with why do not you try this problem first, then this, then this, some three four I would specify and I would be available here, you start solving the problems if there are any questions, they will come and the questions started from there soon after lunch and ended up much beyond the closure time 5.30. Now one of my worries is and I want some suggestions from you is with 31 centers I was comfortable with interaction and that too by providing something like two and a half to three hours every day. We have Professor Puranik there who was part of the fluid mechanics course right and at that time I think you had 46 or 47 centers, okay 48 centers and I may jump the gun but I think I have overheard him saying that he is not sure they have interacted with all the 48 centers sometime or the other, am I right? So they felt a pressure saying with 48 centers it was rather difficult to satisfy each and every center. I have not looked at the feedback if any way they have but you know I have noted by overrearing their comments he and his colleague that and I noticed it because of 31 centers by giving two and a half to three hours a day I was reasonably satisfied and I think those who have participated earlier may comment on this they were also satisfied with the type of interaction we have had at that time. Where you, how many of you were participants, a reasonable number and the interaction was satisfactory right, okay. My colleague Professor Puranik who handled the fluid dynamics course along with Professor Prabhu he was not satisfied when the number of centers became 48 and I am sure they must also have provided a similar slot, similar set of slots for this. Now remember that today we have something like 170 of the prospective workshop coordinators here of centers. It is possible that for some reason a few centers may get deleted last time also it was of course the first thing so 34 became 31 but I would not be surprised if 170 essentially remain 170 because most of you have acted as a center for some course or the other. And because of the exposure of a large number of faculty members there will be a large number of participants also this time. So let us say that if not 170 at least 160 centers we will have. Now how do you manage the interaction with 160 centers with Professor Fartagath said that in the near future we will have just now we have simply a star and a planet right. A star is here and there are 170 planets, 170 centers. Now what is proposed is a tree type of a system the root will be here there will be 10 main branches and from the 10 main branches there will be you know small branches each 10 main nodal centers taking care of maybe 50 individual centers and in each individual centers there will be a few dozen or 50 or 100 participants. So any suggestion about how to handle this? So one way one possible way could be the way they used to and they still do on radio they collect request from almost everybody and when they play that particular song they say this song has been requested by this person that person from here and there. So we can collect questions offline and then during discussion session those questions can be discussed with mentioning okay this question has been raised or proposed by such and such center and then you can answer that question. Yes, so that you know the Fermat type of things something like that we will have to do but remember one difference is that when you want to hear a song well you want to hear it it is not because of something you felt like and it does not matter whether you hear that song now or maybe 10 minutes or 15 minutes later. In this case the questions are going to be based on what the teacher here said a few minutes ago yes but that day same the same day a few I should not say few minutes ago maybe few hours ago okay. So I think that is a good idea so I will talk to the software people maybe on moodle or somewhere we will have those queries coming in then maybe we should have a set of people editing that or collecting that just the way the electronic way of what I am trying to do now with those lips of paper given to you. In fact that I was trying just to see how to handle 170 here later on the 170 will be remote center here I can see 170 of you together at that time your 170 will be each one will be just a small blob here and with a flag going up for a color changing or a flashing indicating that somebody from there wants to talk to us. In fact I had asked in the feedback a question about a general question what do you want to say additionally many people have said with a larger number of centers please improve the interaction you more time for interaction there are a few people we say reduce the interaction it will be just more formal one way teaching I do not like the second one that well if it is more formal one way teaching I could have simply said that look my last time's video lectures are video recorded all I need to do is go through them edit them for any small mistakes here there maybe add something delete something based on some feedback and say look these lectures are available I do not even have to be there I could go to Timbukh too and the course will be just telecast here just the way when some program is telecast on the TV it might have been recorded some interviews with people have been telecast after they have expired that has happened we know it has happened at some time. So I do not want that I want that interaction to take place but then what do you think that interaction should be say all afternoon session should be interaction for most of the afternoon session should be interaction how many of you think because most of you have participated in some after the end of each topic so suppose we will have similar sessions let me go back to this. So let us say the second day in the morning session 9 to 11 we will have something the second law then shall I have the discussion in the 1130 to one session shall I schedule it like that. Is there any possibility that we can collect all questions may be by giving one hour or one and half hour and after that as a cream of the questions so if we start answering that can save time again can lead to particular. No but that what do I do in that one one and half hours what can easily be done in that one because each and every centre will be connected electronically to us because in the video stream of things there is an audio visual transfer both ways going on essentially one way but the second way also reverse is also possible there is also a chat window through that or through a moodle session parallelly can have another PC connected there to the internet and another PC connected here to the internet through the moodle questions can come and then assistants here can you know collate them and tell me at the end of the session during tea time or lunch time that is how the questions are essentially from on these particular topics but then what will happen is and it is possible that the same question may be asked or similar questions may be raised by maybe 15, 20 centres it has happened earlier it has happened that 10 centres have raised their hand I pick up one ask the question here the question make my comments may be take care of a supplementary and then when I go to the other question this is serve they sort of lower their hands because their queries have been answered so such things will be reduced when I have properly collected but from the centre point of view I will not be latching on to a particular centre so the you know the person to person contact which is felt when I latch on to a centre ask a question that will be reduced but I think with 170 centres if I have to complete a task within 10 days I think we will have to give up on some such things of course some interactions I will still have with the centre but just imagine I was doing a calculation that suppose I spend going to a centre listening to them and replying to them it takes say 5 minutes 6 minutes let us take 6 minutes so if I provide 1 hour I will be able to take care of 10 centres if there are 160 centres 170 centres 17 hours are required 17 hours means 3 full days and that too each centre being visited just once I am sure in that old thing with 31 centres I could visit I am sure many centres have been visited every second day or third day if not every day so I think this the personal person to person intensity will have to be reduced in this particular case and as a coordinator you have to appreciate that and let us during this 3 days and even later let us work out a methodology I will set it up most probably we will have a moodle window or a special which act window on which only the questions will be asked and I will have a set of assistants here we will see and collect the yes. Yes what I plan to do is I plan to quickly go through the scheme without much elaboration because I have reduced it to almost half the time see when I reduce it to 5 day to 3 day the first 1 hour or so introduction that cannot be the last day quiz and this so half a day goes there half a day goes here so I have reduced it by 50% so I would go quickly and try to complete okay so essentially we will follow the earlier scheme for the coordinators workshop but at a quick pace now there are two more things which I would like to discuss before if time permits I will have some questions from you this time I said that it is possible for us perhaps to include some additional topics if required but this additional topics definitely would mean deemphasizing if not deleting some of those 13 topics if you look up the candidates I cannot really delete this part but one candidate for significant deemphasis is the significant deemphasis or perhaps deletion is a cycle analysis that is one decision we will have to take one possible candidate is cycle analysis another thing which I think many of you are familiar and hence I would not deemphasize but pick up pace is here open system so once I get some time out of these maybe I should be or we should be able to include some additional topics now a question was which one of these additional which of these additional topics you would like to be you would like to see included so psychrometry essentially the thermodynamics part of psychrometry what is not included in psychrometry is part where you need significant input from heat and mass transfer for example although we will do basic psychrometry processes we will not be able to apply that to say air washers and cooling towers because that becomes really applied psychrometry we are going away from thermodynamics you need significant input from heat transfer and mass transfer the second one was combustion essentially we will do the thermodynamic part of combustion which is stoichiometry and calorimetric but not you know chemical equilibria or kinetics of combustion and all the third one is compressible flow and the fourth one was kinetic theory the response out of 40 was 28 wanted psychrometry to be included 24 wanted combustion to be included 29 wanted compressible flow to be included only 11 wanted kinetic theory to be included now considering that I think is it okay if I say no more kinetic theory discussion we will keep it away probably they are not exposed to kinetic theory. No but let me let me let me ask you in your scheme of thermodynamics I think most of you are in mechanical engineering or related very directly related branch at the undergraduate level is kinetic theory taught or is used is not taught now at all somewhere no right including kinetic theory for mechanical engineers okay so they have one so since we which is your university Bhopal the kinetic theory is included okay so we have so I will put a question mark there bandarkar is looking at me very keenly because he is the default teacher for kinetic theory we will we will take a call on this on the last day of this workshop. Since we at least say there is a microscopic approach this has an introduction I think this kinetic theory should be there I mean at least we should now make an effort to introduce back into the syllabus okay. What about compressible flow and psychrometry no we will see I agree all first three definitely may be kinetic theory is also something which at least at a basic level every mechanical engineering student should learn there is no doubt about it the question is are these going to be a part of a first course or a primary course on engineering thermodynamics for mechanical engineering okay and if so do we have enough time to study these during that 10 day workshop because you know finally there is a constraint on time and in that time we can go at say frontier male speed or Rajdhani express speed but then the absorption of US coordinators and the participants as participants you know doing too much in a short time the rate of absorption and finally the understanding will not be very significant maybe it is a good idea to reduce the number of topics likely but do excellent learning of those topics at the individual level there is enough time later to learn additional topics or additional subjects for the 10 days I think yes I have I am going to significantly de-emphasize cycles maybe at the end of this workshop we may say that we will not talk of cycles in that my point is the psychrometry and combustion compressible flow will all be taught in thermal engineering later okay so it is not necessary to cover it in the fundamental course in thermodynamics okay that is your this is for psychrometry and psychrometry, combustion and the compressible flow will be a full course so your thing is restrict to the first 13 topics okay and I would still support kinetic theory because normally it is not coming even afterwards so small amount of kinetic theory will be good okay sir my I agree with the two topics that were told by that sir compressible flow not necessary and combustion is also not necessary but in our JNTU and Antupoor syllabus we are having this psychrometric process so we can discuss there for that 10 day workshop. So let us have an open discussion panel I get a feeling that there sufficient interest at least to begin with in the first three topics definitely and also in kinetic theory so may I propose that on the last day beginning with 9 o'clock and ending at most up to lunch that is two hours and one and a half hours so you have totally three and half hours at most okay you need not use all give them a either a Jalak or a trailer or a what they say the pilot episode of a serial called psychrometry, combustion, compressible flow kinetic theory that means since you have about three hours say about 30 to 45 minutes for each followed by may be 10, 15 minutes for discussion and all possible no teaching saying what you will do what you will derive what way it will be done what type of exercises will be done you can even bring a few slides of you know some exercises and say this is the typical problem and we will be using this possible. So your job is psychro combustion kinetic theory, this job is compressible flow it is left between you to exchange topics if you feel great advantage of we get teacher of a coordinate okay. So I think that is agreed that we will have on third day morning a an idea of what is involved in our scheme of teaching of psychrometry, combustion, compressible flow and kinetic theory in psychrometry as we say we will restrict only to the psychrometric systems basic psychrometric processes and psychrometric properties and we will not go into applications like air washers and cooling towers essentially what we do basically. In combustion we will restrict to basic descriptions of fuels basic idea of combustion stoichiometry and some calorimetry then coming to compressible flow one dimensional steady compressible flow of an ideal gas with constant specific heats so that the algebra is simple and velocity of sound one dimensional converging diverging ducts that means nozzles and diffusers and may be normal shock I think that is up to that point is good enough and kinetic theory you decide those yeah, yeah, yeah so it is needed I am just giving them and you a hint of what is to be expected this is just an advertisement short break for what is happening on like likely to happen on Friday okay so Friday morning UVB plus BP okay now the next thing is I think all of you have this thing in your packet okay I think it is a mental set that mechanical engineers work with essentially two fluids they cannot breathe without those two one is air and one is water steam in some form or the other since air is a much simpler fluid we generally make do with algebraic equations for its properties that is not true for water and steam so we have to have steam tables there is nothing special about these steam tables one of us discovered this way back in the 80s when it was much thinner than this and after that we found that it is good enough it was also cheap enough even now I think it is some 20 or 24 rupees at that time it was when I first bought it it was 4 rupees or so the Mollier chart has been added earlier it was not included and this is good enough for undergraduates I am sure there are equivalent steam tables and I had requested you to bring the steam table which you use so that when we discuss properties of steam if there are any issues pertaining to this steam table or other steam table we will have it for discussion so I think all of you should have it with you in the one of the issues which we will have to discuss is that in the final workshop we will have a few quizzes some two quizzes I plan to have one at the end of the first week and one on the ninth day or tenth day morning but one thing we were not really satisfied with from the last workshop was the feedback and submissions from the participants at the end of the workshop so this time Professor Fatak and the NMEI city the main central committee has decided that we must have a reasonable contribution from each participant or a group of participants before the certificates are handed out the certificate should not be handed out only for attending and participating in the workshop so one thing is there will be two quizzes it will be necessary for the candidate participant to appear for each one of these two quizzes and it will be necessary for the participant or a group of participants if we decide to submit an assignment and during these three days we will see what type of assignments are possible there are some three schemes which I have already thought about and we will propose those three schemes and we will give a choice that a team of participants say between 5 and 10 that also we depend on the number of participants will either do an assignment of type A or assignment of type B or assignment of type C one will be exercises one will be creation of a set of slides I will demonstrate what I have in mind or helping out with some sort of a spoken tutorial I will show that also so that is another thing which we have to do so it is 1045 so let us take a break
