In a single pass, cross flow heat exchanger where two fluids are not mixed, water with a temperature of 35oC, a mass flow of 1 kg / s, a specific heat capacity of 4197 J / kgK, 250oC, a mass flow of 1.5 kg / s, a specific heat capacity of 1000J / kgK. heated by hot gas. If the heat transfer area of the heat exchanger is 40 m2 and the total heat transfer coefficient is 100 W / m2K, calculate the exit temperatures of the water and hot gas from the heat exchanger using the NTU 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.
