Water is used in a regenerative power cycle, where the standard Rankine cycle is augmented with one closed feed water heater that uses turbine steam extracted at 100 lbf/in2. The condensate from the heater is trapped into the condenser. The pressure and temperature at the turbine inlet are 1200 lbf/in2 and 1000 F, respectively, and the condenser pressure is 1 lbf/in2. The mass flow rate of steam entering the turbine is 1.4 million lb/h. The cooling water experiences a temperature increase from 60 to 80 F, with negligible pressure drop, as it passes through the condenser. The turbine efficiency is 88%, while the pump efficiency is 80 %. Determine for the cycle the net power developed, in Btu/ h.
