Consider a 200-MW reheat-Rankine-cycle steam power plant. Superheated steam enters the high-pressure turbine at 1000 K and 12 MPa. The steam enters the reheater at 800 K and 3 MPa and is reheated at constant pressure to 1000 K. It expands through the low-pressure turbine and enters the condenser as saturated vapor at 50 kPa. The water enters the pump as a saturated liquid at 50 kPa. 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.
