 So welcome back we had just seen a case where the pressure was less than the critical pressure when the given P was less than critical pressure for water that means the pressure was less than 22 MPa. Now let us see table 3 for subcooled and supercritical zone now that means when the pressure is above the critical pressure that means the pressure is more than 22 MPa. So this is the table now for a case I am talking about and you can see that I am talking about the pressure equal to 25 MPa which is more than 22 MPa and therefore if I draw a horizontal line here I can see that this is now supercritical pressure so I am at 25 MPa in a subcooled compressed liquid zone and if I go on increasing temperature now here from 0 degree centigrade to 1000 degree centigrade I will not come across this LV saturation line that means I will not have a corresponding value of T set P over here and that is why you can see nothing has been given in the bracket till the pressures which are below the critical pressures all this steam tables table 3 would give you T set P value in the bracket over here but the moment you see that in the table 3 nothing is given in the bracket you should be sure that this pressure is beyond the critical pressure obviously we know that 22 MPa is the critical pressure for water and the moment we know that there is no T set value associated with that because it is beyond critical pressure you will not hit a LV line and therefore you do not see any T set value given in this table as was given earlier alright so if I go on increase the temperature I will not come across a T set value and I will not come across any latent phase change over here because there is no phase change line that I encounter when I go on increase the temperature from left to right just to show you again some points 50 degree centigrade at higher pressure if I compare with earlier pressures of 0.1 MPa I mean this region now this was the phase change point earlier case in this case now I am at 115 degree centigrade but earlier case I was at low pressure and therefore I was in a super heated vapor zone now I am in a sub cooled compressed liquid zone so just by changing the pressure by increasing the pressure I have changed the zone now in this case similarly one more case of 400 degree centigrade I am in a super critical fluid zone now alright so this is my super critical zone this these two points are shown in sub cooled zone and as I shown that if I went on increase the temperatures I will not come across any latent phase change. So what have we learnt from this we have seen steam tables and we have specifically seen table 3 which is meant for single phase regions we saw sub cooled and super heated zone earlier and then we saw sub cooled and super critical zone in the last slide. Thank you very much.
