as Question 2 (7.5 Marks It is desired to design a 1-2 shell-and-tube heat exchanger for cooling down ethylene glycol with a flowrate of 0.5 kg/s from 100C to 60C using water the cooling medium having a temperature of 10C. The ethylene glycol will be flowing through a thin-walled copper tube of 1.25 cm diameter. The overall coefficient is 2900 J/m.K whereas the heat capacities for the ethylene glycol and water are 2650 and 4180 J/kg.K, respectively. a) Calculate the length of the tube required. b) Calculate the length of the tube required if the heat exchanger is a countercurrent flow double-pipe heat exchanger
