Mechanical Engineering

This is problem 7-12 from El-Wakil’s Powerplant Technology book-- it is desired to compare the effect of two types of dry coolingtower systems on powerplant performance. The towers are of theindirect cooling type. One operates with a surface condenser withan 8 degrees Fahrenheit terminal temperature difference, and theother with a direct-contact condenser with 0 degrees Fahrenheitterminal temperature difference. Consider for simplicity a simpleideal Rankine cycle with inlet saturated steam at 1000 psia.Further consider that both have the same condenser cooling watermass flow rate of 7.21x107 lbm/h, the sameinlet temperature of 70 degrees Fahrenheit, the same dry tower airtemperature range of 60 degrees Fahrenheit in and 90 degreesFahrenheit out, and the same air mass flow rate of 5x108lbm/h. Calculate for each case (a) the condensertemperature, in degrees Fahrenheit, and pressure, in psia, (b) thesteam mass flow rate, in pound mass per hour, (c) the cycleefficiency, and (d) the cycle work, in megawatts, ignoring the pumpwork.
