A gas turbine exhaust stack cooler drops the gas temperature from 1020oF to 605°F by means of a water cooling coil. Cooling water enters the coil at 65°F and leaves, after a counter-flow passage, with a temperature of 190°F. If cp for the gas is 0.26 Btu/lb.F, calculate the overall heat transfer coefficient for an exchanger area of 2000 ft2, Btu/hr.ft2.F.
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
