 So, welcome back. What we have seen till now is the basic introduction to the fluids. We saw the Gibbs phase rule. We understood the importance of properties of fluids, property of water and I had just said something about steam table. Taking ahead from there, let us see the outline of this lecture. I will again go through the details of the steam tables. How to see the steam tables? Then I will introduce you to steam table, table number 1 and table number 2. We will just see those tables and we will see the steam table itself. All right. Now, when we see steam tables, it has in that book, we have got 3 tables, table number 1, table number 2 and table number 3. The table number 1 and 2 actually talk about saturation line only, the LV line, the liquid vapour saturation line. The only difference being it has got different bases for comparison. For example, base is temperature here and base is pressure and we will see that in detail. What do you mean by these bases? While the table number 3 deals with single phase region. So, saturation line talks about 2 phases also, saturated liquid, saturated vapour and liquid plus vapour region that is going to be covered by this table number 1 and table number 2. So, table number 1 and table number 2 talk about LV saturation line, liquid vapour saturation line. Obviously, it means therefore, it deals with liquid vapour saturation line from TP to CP, triple point to critical point and we have talked about this earlier. While the table number 3 deals with single phase regions and what these regions are? This is a subcooled water region which is on the left side of this LV line and you got a superheated region which is on the right side of this LV line. So, first 2 tables talk about the LV line itself while the table number 3 talks about single phase region. This may be subcooled region, this may be superheated region or even supercritical region, alright. This is single phase region. Now, let us see the steam table itself. Let us just have a look at steam table itself and then we will come back to these slides again. So, this is what we call a steam table. The title reads as properties of water and steam, thermodynamic properties of ordinary water. If I go down this is for this course, specially made for this course, it is based on the NIST steam tables, National Institute for Standards and Technology in Colorado for ME209X thermodynamics edX and IIT Bombay X. This is specially made for this course based on what is available at NIST, website NIST steam table. If I could come further down, this is IIT Bombay August 2014. The introduction talks, these tables are created using NIST steam tables. The link also has been given over there. The data has been taken from here and it has been modified for our purposes. Please go through all these introductory remarks on this steam tables. The nomenclature also has been given. The property data that we get from this steam table also has been given here in which units. So, detailed information has been given in this steam tables. Now, what I told you earlier, the table 1 is talking about saturation line. It talks about saturation line, LV line, the basis temperature. I will just show you table 2 and table 3 in this way and then we can come back to the lectures. This is table 2, saturation line, base pressure and this is what it reads, table 3, water sub cooled oblique steam superheated. That is it. These are these three tables in this steam table and what we are going to read is the properties of steam or water, liquid, liquid plus vapor etcetera at different pressures and temperatures. Thank you very much.
