Water (cp = 4182 J/Kg.K) at a flow rate of 45500 Kg/hr is heated from 80oC to150oC in a shell and tube heat exchanger having two-shell-passes and eight-tubepasses with a total outside heat transfer surface area of 925 m2. Hot exhaust gaseshaving approximately cp as air (cp = 1050 J/Kg.K) enter at 350oC and exit at175oC. Determine the overall heat transfer coefficient based on the outside surface area of the heat exchanger.
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.
