A counter-flow double-pipe heat exchanger is to heat water from 29ºC to 90ºC at a rate of 1.5 kg/s. The heating is to be accomplished by hot liquid available at 180ºC at a mass flow rate of 2.3 kg/s. The inner tube is thin-walled and has a diameter of 18 mm. If the overall heat transfer coefficient of the heat exchanger is 760 W/m2ºC, determine the length of the heat exchanger required to achieve the desired heating. The specific heats of water and hot fluid are 4.22 and 4.35 kJ/kg ºC, respectively.

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.
