PLZ I want full answer with all solution steps 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) note: Assume any values for the missing data

he shell fluid,ethylene glycol, enters at 120oC and leaves at 60oCwitha flow rate of 4000 kg/h. Water flows in the tubes, entering at 35oCand leaving at85oC. The overall heat-transfer coefficient for this arrangement is 900W/m2·oC.The exchanger is a shell tube with two shell passes and two tube passes.Calculate the following: a) The water exit temperature if flow rate of glycol to the exchanger is reduced in half with the entrance temperatures of both fluids remaining the same and by how much is the heat-transfer rate reduced?; b) The percentage reduction of heat transfer if water-flow rate is reduced by 25percent,while the gas flowrate is maintained constant along with the fluid inlet temperatures.
