A steam Rankine cycle operates between the absolute pressure limits of 10 MPa in the boiler and 20 kPa (absolute) in the condenser. The turbine inlet temperature is 815°C. 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 absolute pressure limits of 10 MPa in the boiler
and 20 kPa (absolute) in the condenser. The turbine inlet temperature is 815°C. 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.
