A crossflow heat exchanger uses oil (Cp =2.1 kJ/kg · oC) in the tube bank with an entering temperature of 100oC. The flow rate of oil is 1.2 kg/s. Water flows across the unfinned tubes and is heated from 20 to 50oC with a flow rate of 0.6 kg/s. If the overall heat-transfer coefficient is 250 W/m2 · oC, calculate the area required for the heat exchanger using LMTD method.
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.
