A double tube heat exchanger will be used to cool bezene from 82 Celsius to 38 Celsius. water enters the annular space at 21 Celsius, flows countercurrent with benzene at 1.5 m / s, exiting at 37 Celsius. The internal tubing is 1 1/4 inch cd 40 of commercial steel. The outer tubing is 2-inch Cd 40 steel. What is the heat transfer coefficient that would be expected for water?
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.

the fluid moves in the annular space of the two tubes that are concentric. there is a formula for that.
