Compare the thermal efficiency and turbine-exit quality (temperature if superheated) at the condenser pressure for a simple Rankine cycle and the reheat cycle when the boiler pressure is 5 MPa, the boiler exit temperature is 500°C, and the condenser pressure is 20 kPa. The reheat takes place at 0.5 MPa and the steam leaves the reheater at 500°C. (Enthalpies are in KJ/kg.) Without the reheater, the heat added is: The enthalpy entering the condenser is: The net Work is: The enthalpy entering the reheater is: Without the reheater, the net Work is:
