A reheat cycle with two stages of reheating is executed, with steam expanding initially from 2250 psia and 1060 0F. The two reheater pressures are 580 psia and 150 psia, and steam leaves each reheater at 1000 0F. Condensation occurs at 40 psia. Find a) the cycle efficiency, % b) the steam rate, in kg/kwhr c) if there is no reheater compute for the exhaust enthalpy if the efficiency of turbine and pump are both 82% and d) find its thermal efficiency.
