Extracted text: A hot oil is to be cooled by cold water in one shell-pass 8 tube passes heat exchanger. If the surface area of the pipes is 3 m? and the overall heat transfer coefficient U is 315 W/m.K. The cold water enters the tubes at 20C with a mass flow rate of 0.4 kg /s and the oil enters the shell at 150°C with a mass flow rate of 0.6 kg /s. Take c, for water as 4.20 kJ/kg.°C and for oil as 2.10 kJ/kg.K. Calculate a) The heat transfer rate for this heat exchanger b) The outlet temperature of water .c) The outlet temperature of oil Oil Water
