A steam Rankine cycle operates between the pressure limits of 1500 psia in the boiler and 2 psia in the condenser. The turbine inlet temperature is 800F. The turbine isentropic efficiency is 90 percent, the pump losses are negligible, and the cycle is sized to produce 2500 kW of power. Calculate the mass flow rate through the boiler, the power produced by the turbine, the rate of heat supply in the boiler, and the thermal efficiency.

Question
A steam Rankine cycle operates between the
pressure limits of 1500 psia in the boiler and 2 psia in
the condenser. The turbine inlet temperature is 800F. The
turbine isentropic efficiency is 90 percent, the pump losses
are negligible, and the cycle is sized to produce 2500 kW of
power. Calculate the mass flow rate through the boiler, the
power produced by the turbine, the rate of heat supply in the
boiler, and the thermal efficiency.
