A shell-and-tube heat exchanger with one shell pass and four tube passes has 4.83 m2 of heat-transfer area. The overall heat transfer coefficient is 320 W/m2 ·K. It is proposed to cool a stream of oil (cp = 2.22 kJ/kg·K) at 120 °C, flowing at 1.50 kg/s, with cooling water available at 13 °C and a flow rate of 0.63 kg/s. Determine the exit temperatures of the two streams.
