Consider the following (real) vapour power plant process in Figure 1. Fresh steam (point 3) temperature is 480 ° C and pressure 50 bars. The isentropic efficiency of the turbine (?T) is 0.93 and the isentropic efficiency of the pump (?P) is 0.86. The condenser heat rate is 42 MW and the condenser pressure is 0.05 bar. You can assume that water will condense into a saturated liquid in the condenser. a) Determine the net mechanical work of the process (2 p) b) Determine power plant thermal efficiency (?th) and the Carnot efficiency (?max) (2 p) c) What is the power output of the turbine (2 p)
