A shell-and-tube heat exchanger with two tube passes and baffled single shell pass is used as oil cooler. Cooling water at 20°C flows through the tubes at a flow rate of 4.082 kg/s. Engine oil enters the shell side at a flow rate of 10 kg/s. The inlet and outlet temperatures of oil are 90°C and 60°C, respectively. The overall heat transfer coefficient based on the outside tube area (Uo) is 262 W/m2⋅K. The specific heats of water and oil are 4.179 kJ/kg⋅ oC and 2.118 kJ/kg⋅ oC, respectively.
