Water is the working fluid in an ideal regenerative Rankine cycle with one closed feedwater heater. Steam enters the turbine at 1400 Ibp/in.² and 1000°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. Step 1 Determine the mass flow rate of steam entering the first stage of the turbine, in lb/h. m1 = Save for Later lb/h Attempts: 0 of 4 used Submit Answer
