Question
A straightforward Rankine cycle utilises water as the working fluid. The boiler runs at a pressure of 7000 kPa and the condenser at a pressure of 50 kPa. The temperature at the turbine's entry is 450 degrees celcius. The turbine is isentropically efficient at 90%, pressure and pump losses are low, and water exiting the condenser is subcooled to 6.32 degrees celcius. The boiler has been designed to operate at a mass flow rate of 20 kg/s. Determine:
a) The rate of heat addition in the boiler b) The amount of energy needed to run the pumps
c) The cycle's net power output and thermal efficiency
