2UESTION 3(30p) The process fluid, whose properties are given below, is desired to be cooled. For this purpose, 1-2 type heat exchanger will be designed. The process fluid will be cooled from 473 K to 368K at a volume flow rate of 0.037m/s in the jacket section of the heat exchanger. The refrigerant will enter the heat exchanger at 35C and leave 75C. Since the overall heat transfer coefficient (U) is 258W/mC, using the following data according to the Kern method; a) Calculate the jacket side film heat transfer coefficient. b) Since the pipe side film coefficient is 520W/m2K, ignoring the pollution resistances, U.' Check and comment the result. c) Since the inlet pressure of the process fluid to the jacket is 2atm, calculate the jacket side pressure drop and interpret the result. 2UESTION 3(30p) The process fluid, whose properties are given below, is desired to be cooled.
