Consider a standard steam power plant operating on the ideal Rankine cycle. The boiler is heated by the burning of natural gas. The upper pressure is 8 MPa and the condenser temperature is 40C. The turbine inlet temperature at state point 3 is 574C. The feedwater pump and turbine are irreversible with isentropic efficiencies np = 0.85 and T = 0.88, respectively. The steam quality at the exit of the turbine, x4, is 90%. The steam flowrate is 70,000 kg/h. 1. 2. Show the entire cycle on a detailed p-h diagram. (5 points) Calculate the power required to drive the feedwater pump. (10 points) 3. Determine the rate of heat transferred in the boiler. (5 points) 4. Determine the power output of the turbine (or turbines). (5 points) 5. Determine the rate of heat rejected to the cooling water in the condenser. (5 points) 6. Determine the thermal efficiency of the power plant. (5 points)
