A thin-walled double-pipe counter-flow heat exchanger is used to cool oil (C, = 2.20 kJ/kg.°C) from 150 to 40°C at a rate of 2 kg/s by water (c, = 4.18 kJ/kg.°C) that enters at 22°C at a rate of 1.5 kg/s. Determine the rate of heat transfer in the heat exchanger and the exit temperature of 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.
