Double-pipe heat exchangersare used in many industries because of their low design and maintenance costs, flexibility, and low installation cost. They are mainly used for sensible heating or cooling of process fluids in applications of small heat transfer Water at the rate of 68 kg/min is heated from 35 0C to 75 0C by an oil having specific heat of 1.9 kg/kJ.0C . The fluids are used in a counter flow double-pipe heat exchanger, and the oil enters in the exchanger at 175 0C and leaves at 140 0C . The overall heat transfer coefficient is 320 W/m2. 0C . Apply heat transfer formulae to heat exchangers and calculate the heat exchanger area.
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.
