A one-shell pass and two-tube passes heat exchanger must transfer 300 kW to a solution with a specific heat of 3.28 kJ/kg-K and change its temperature from 60 C to 88 C. Steam is available at 120 C. The unit convective coefficient is 3200 W/m2-K for the inside and 8500 W/m2-K for the outside. The thermal conductivity for the tubes is 115 W/m-K and the tubes have 4 cm OD and 3 cm ID and are 3 m long. Determine the number of tubes required.
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.
