Q1) A heat exchanger is to be designed to heat 32/68 mixture of ethylene glycol and water from 24 ᵒC to 55 ᵒC by a hot water stream from 79 ᵒC to 42 ᵒC. Flow rate of cold stream is 20 kg/s. Inlet pressure for both stream is 50 psi and the maximum pressure drop of 10 psi for cold stream and 8 psi for hot water are permissible. Report valid assumptions made for the design and give required justification. Estimate Heat Transfer, Corrected LMTD, Tube bundle diameter (Using TEMA standards and Codes) and Tube cross sectional area Heat transfer coefficient Overall heat transfer coefficient Pressure Drop (Shell side & Tube Side)
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.
