(a) Draw P-H and T-S diagrams for following cases : (3) (i) Cycle with superheated vapour before compression. (ii) Cycle with sub-cooling or under-cooling of refrigerant.
The steam that leaves the super-heater is expanded from 130bar at 535°C to 25.2bar at 310°C in a high pressure turbine. The steam from the exit of the HP turbine is reheated to 535
