Consider a 600-MW reheat-Rankine-cycle steam power plant. The boiler pressure is 1000 psia, the reheater pressure is 100 psia, and the condenser pressure is 1 psia. The exit temperatures of the boiler and the reheater are both 1000 F. The turbines and the pump have isentropic efficiencies of 0.90 and 0.85, respectively. The water leaving the condenser is saturated liquid. Determine the thermal efficiency of the power plant.
