Consider a power plant operating on an ideal Rankine cycle without feed water heating. Steam enters the turbine saturated at 1000F at the rate of 5 x10 lbm/H. The turbine exhausts to a surface condenser at 1 psia. The condenser has an overall heat transfer coefficient of 435 Btu/h*ft^2, a heat transfer surface area of 402467 ft^2 and cooling water inlet temperature of 60F. 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 in cubic feet per minute.
Superheated steam in a piston-cylinder device is initially at 200 °C, 600 kPa. Heat is removed from the system during an isobaric process until half of the mass condenses to saturated liquid
