2 - shell pass & 4 - tube pass heat exchanger is designed to heat water from 40 C to 90 C flowing inside the tubes at a rate of 7.5 kg/sec while hot gases flowing in the shell at a rate of 10.42 kg/sec with temperature leaving the heat exchanger at 110 C. Consider the specific heat of water and gas of 4.2 kJ/kg K & 1.08 kJ/kg K, respectively. Draw the temp-profile showing the multi-pass effect and determine the temperature of gas entering the heat exchanger.
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.
