It is required to evaluate the effects of changing surface condenser size on power plant performance. Consider for simplicity an ideal rankine cycle without feed water heaters. the turbine inlet steam is saturated at 1000 psia and has a mass flow rate of 5 x 10^6 lbm/h. Condenser cooling water is available at 60F. For a condenser heat transfer area of 402467 ft^2 and overall heat transfer coefficient of 435 Btu/h*ft^2, the condenser operates at 1 psia. Now consider that the same plant operates with a condenser that has 15 percent more tubes and 15 percent more cooling water flow. Calculate (a) the new exit water temperature in degrees Fahrenheit (b) the new condenser pressure in pounds per square inch absolute and (c) the new plant power in megawatts and efficiency. Assume that the overall heat transfer coefficient is unchanged.
