A steam Rankine cycle operates between the pressures of 2500 psi in the boiler and 1 psi in the condenser. The turbine inlet temperature is 800°F. The turbine's isentropic efficiency is 90% and the pump can be considered ideal. The cycle is sized to produce 1000kW of power. Calculate:
a) the mass flow rate through the boiler
b) the power produced by the turbine
c) the rate of heat into the boiler
d) the thermal efficiency
