1. POWER GENERATION CYCLE. A power generation cycle is operated with water as the working fluid. Steam enters the turbine at 5300 kPa and 650 °C and leaves at 101.3 kPa. It is found that 1052.2 kJ of work is produced in the turbine per kg of steam. The turbine operates adiabatically but not reversibly. The pump operates adiabatically and reversibly. Saturated liquid exits the condenser. Take a basis of 1 kg of steam. a) What is the enthalpy of the steam (kJ) leaving the turbine under the given operating conditions? b) What is the temperature of the steam (°C) leaving the turbine under the given operating conditions? c) How much work (kJ) would have been produced if the turbine operated adiabatically and reversibly between the given inlet conditions and at the exit pressure of 101.3 kPa? d) What is the isentropic efficiency of the turbine? e) How much heat is discarded from the condenser (kJ)? f) How much work is needed to operate the pump (kJ)? g) What is the efficiency of the power cycle?
