Consider a 100-MW reheat-Rankine-cycle steam power plant. Superheated steam enters the high-pressure turbine at 800° C and 10MPa. The steam enters the reheater at 700° C and 4MPa and is reheated at constant pressure to 800° C. The steam expands through the low-pressure turbine and enters the condenser as saturated vapor at 0.01MPa. The water enters the pump as a saturated liquid at 0.01MPa. The turbines and pump are adiabatic. The pump is reversible. Determine the thermal efficiency of the power plant and mass flow rate (kg/s) of the steam.
