This is problem 6-6 from El-Wakil’s Powerplant Technology book -- consider a powerplant operating on an ideal Rankine cycle without feedwater heating. Steam enters the turbine saturated at 1000°F at the rate 5x106 lbm/h. The turbine exhausts to a surface condenser area of 402,467 ft2 and cooling water inlet temperature of 60°F. Calculate (a) the plant net power, in megawatts, (b) the plant efficiency, in percent, (c) the cooling water exit temperature, in degrees Fahrenheit, and (d) the water flow rate, in pound mass per hour and cubic feet per minute.
