Hot water enters at 46 ° C and leaves at 37 ° C, and cold water enters with 19 ° C to a well insulated adiabatic counter flow tube heat exchanger. The flow of hot water is 20 l / min and the flow of cold water is 800 l / h. The heat transfer surface area is 0.61 m2. (c = 4.18kJ / kgK, p = 998 kg / m³) a) Find the heat transfer coefficient. b) Draw the temperature distance (T-x) graph. (h = hot, c = cold fluid.)

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.
