A counterflow, concentric tube heat exchanger used for engine cooling has been in service for an extended period of time. The heat transfer surface area of the exchanger is 5 m², and the design value of the overall convection coefficient is 38 W/m²K. During a test run, engine oil flowing at 0.1 kg/s is cooled from 110 °C to 66 °C by water supplied at a temperature of 25 °C and a flow rate of 0.2 kg/s.

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.
