Hot oil ( Cp=2200 j/kg.°C) is to cooled by water (Cp=4180 j/kg.:°C) double pipe [shell- tube] heat exchanger and the tube thin walled made of copper with a outlet Diameter = 35 mm while the inlet diameter = 20 mm. The overall heat transfer Coefficient is (550 w/m?.°C), water flow at a rate of (3325 kg /hr) and the oil flow at a rat of (3425 kg /hr) . the water enter at [18 --52°C ] and the oil enter at [ 160 °C 7. Determine : (1) rate of heat transfer (2) length 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.
