 So, welcome back, we had just seen that after referring to table 1, how did we decide in which zone the given state lies? Let us refer to table 2 because the same exercise can be done by using table 2, earlier we had used table 1. So, this slide now will understand if I were to use table 2, how do I identify different zones for a given state? So, again I will go back to PT diagram here and now I have been given PT value over here, alright. So, given PT now because I am referring to table 2, my reference point becomes P now pressure and corresponding to this given pressure, I will get the value of T set P now, is not it? For a given P, I will go to table 2, locate that value of P and get correspondingly the T set P value for that pressure. The find T set P and the first case again, if this T happens to be T set P, the given T value is equal to T set P, if that is possible then I know that our system lies on a saturation line. As was the case with table 1, when the pressure was equal to P set T, here the first case is referring to temperature is equal to T set P, if that is possible that means this state lies on saturation line, LV saturation line. It also means that the given point is nothing but P set T and T set P alright, the coordinates of these points are respective saturated pressures and temperatures. The second case now, I am comparing temperature here and if this temperature happens to be more than the T set P value over here, so in case my T is more than T set P, the state lies in a super heated vapor zone as shown over here. So, second case if T is more than T set P, the state lies in super heated vapor zone alright. Now, the third case is if temperature is less than T set P then obviously, the state lies in a succuled or compressed liquid zone, I think it is very simple to understand from here now. I am just comparing temperature with the T set P value and the fourth case is the same case as what we had seen earlier, if the pressure and temperatures are beyond the critical limits, T is more than T critical and if P is more than T critical, then the system lies in a super critical fluid zone or the state is in a super critical fluid zone as shown over here. Thus, by using table 2 now and by comparing temperature T set P with given temperature, we can identify that given state lies in which zone of all these four zones we can find out in which zone it lies. So, in summary I can show that from table 1, I can compare the pressure for a given temperature and from table 2, I compare the temperatures for a given pressure. So, T set is the given value and compare T with this T set and compare P with this P set. So, these two tables actually is summary of what we saw just now by referring to table 1 and table 2 in order to decide a particular state lies in which zone. So, what have we learnt? We have seen that how to identify a given thermodynamic state in which zone it belongs to on a P T diagram. We have seen that zones on P T diagram by referring to table 1, we compare the value of pressure with P set and in table 2, we compare the value of T with T set. Thank you very much.
