Steam enters the high-pressure turbine at 12.5 MPaand 550° C at a rate of 7.7 kg/s and leaves at 2 MPa. Steam is then reheated at constant pressure to 450°C before it expands in the low-pressure turbine. The isentropic efficiencies of the turbine and the pump are 85% and 90%, re- spectively. Steam leaves the condenser as a saturated liquid. If the moisture content of the steam at the exit of the turbine is not to exceed 5%, then make all the necessary assumptions and determine (a) the condenser pressure, (b) the net power output, and (c) the thermal efficiency. Draw an accurate T-s diagram of the cycle and label all the property values on this diagram. (3 High-P Turbine Low-P 4 Turbine Boiler Reheater 6) (Pump- Condenser (1) Fig. Q 2
