Question
Water is the working fluid in an ideal regenerative Rankine cycle with one closed feedwater heater. Steam enters the turbine at 1400
lb/in.² and 1200°F and expands to 120 lb/in.2, where some of the steam is extracted and diverted to the closed feedwater heater. The
remaining steam expands through the second-stage turbine to the condenser pressure of 2 lb/in.² Condensate exiting the feedwater
heater as saturated liquid at 120 lb/in.² undergoes a throttling process as it passes through a trap into the condenser. The feedwater
leaves the heater at 1400 lb/in.² and a temperature equal to the saturation temperature at 120 lbf/in.² The net power output of the
cycle is 283 MW.
