A heat exchanger is to be designed to heat 32/68 mixture of ethylene glycol and water from 24 °C to 55 °C by a hot water stream from 79 °C to 42 °C. 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 i) Heat Transfer, Corrected LMTD, ii) Tube bundle diameter (Using TEMA standards and Codes) and Tube cross sectional area iii) Heat transfer coefficient iv) Overall heat transfer coefficient v) Pressure Drop (Shell side & Tube Side)
