condenser pressures to obtain highest thermal efficiency and lowest ssc. In an actual Reheat-Rankine. 15 kg/s superheated steam enters the High-Pressure turbine at PBbar, 400°C.The steam expands through the first-stage turbine to (Pi) bar and then reheated to400°C. The turbine efficiency is (n) and the pump isentropic efficiency is 90%. The condenser pressure is Pc bar. Determine the following: 1. Quality at the exit of the first stage turbine 2. The thermal efficiency 3. SSC 4. The condenser Load. Plot the below requirements against Pi and comment on the trend of each curve. Use P-1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 22, 24, 28, 30, 35, 38, 40, 45, and 50 bar.
