Superheated steam at 10 MPa and 480C leaves the steam generator of a vapor power plant. The power plant is operated by a Rankine cycle (may not be ideal). The pressure at the exit of the turbine is 10 kPa, and the turbine operates adiabatically. The mass flow rate of the fluid is 80 kg/s. The power output in the turbine is 65 MW. Assume both the pump and turbine are adiabatic and the isentropic efficiency of the pump is 100%. Neglect potential and kinetic energy changes. a) Calculate the isentropic efficiency of the turbine. b) If the specific enthalpy at the exit of the pump is 203.2 kJ/kg, what is the heat transfer rate in the boiler? Calculate the thermal efficiency of the cycle. Neglect the power to run the pump. c) What is the maximum power output of the turbine if the turbine is operated reversibly? What is the maximum thermal efficiency of the cycle? Neglect the power to run the pump.
