Water is the working fluid in an ideal regenerative Rankine cycle with one closed feedwater heater. Steam enters the turbine at 1400 lbf/in.2 and 1200°F and expands to 120 lbf/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 lbf/in.2 Condensate exiting the feedwater heater as saturated liquid at 120 lbf/in.2 undergoes a throttling process as it passes through a trap into the condenser. The feedwater leaves the heater at 1400 lbf/in.2 and a temperature equal to the saturation temperature at 120 lbf/in.2 The net power output of the cycle is 288 MW. Determine for the cycle:(a) the mass flow rate of steam entering the first stage of the turbine, in lb/h.(b) the rate of heat transfer, in Btu/h, to the working fluid passing through the steam generator.(c) the percent thermal efficiency.
