In a Rankine cycle with a single stage of reheat, steam leaves the boiler at 3.5 MPa and 400degC and expands to .5 MPa in the high pressure turbine, after which is is reheated to 400degC and expanded to 7.5 kPa in the low-pressure turbine. Water is discharged from the condensor to the pump at 30degC. If the turbines and pump are adiabatic, with isentropic efficiencies of 80% each, and the combined power output of the two turbines is 10MW, find: A) the mass flow rate of the system B) the power output required by the pump C) the thermal efficiency of the cycle
