4. T - (Temperature vs. Specific Volume) Diagrams:
a. 15 marks
Plot the phase change process of a fluid at three different pressures P1 < P2 < P3 and show how you can determine the critical point (C) of the fluid.
b. (15 marks)
Identify in the diagram the regions corresponding to the different phases of the fluid.
Critical
COMPRESSED LIQUID REGION
SUPERHEATED VAPOR REGION
SATURATED LIQUID-VAPOR REGION
