A shell &tube heat exchanger has 4 tube passes. Oil inters to the tubes with 100oC . Mass flow rate of the oil is 3 Kg /s and its heat capacity is 2.1 Kj/KgoC. In the shell side air passes with 2 Kg /s Mass flow rate and 1.009 Kj/KgoC heat capacity. Input temperature of air is 20 oC and output temperature is 80 oC. Overall heat transfer coefficient is 200 W/m2 oC. Considering outer diameter of tubs 2cm and tube length 2 m, determine number of tubes in each pass
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.
