A Rankine cycle with superheat uses water as its working fluid. Superheated steam exits the steam generator at 1800 psia and 1100°F and exits the condenser as a saturated liquid at 4 psia. The mass flow rate of the water is 250 lbm/s. Determine the net power produced, the exit state of the water from the turbine, and the thermal efficiency of the cycle if (a) the turbine and pump are isentropic, and (b) the turbine isentropic efficiency is 75% and the pump isentropic efficiency is 67%.
