Hot oil (cp = 2200 j/kg·k) is to be cooled by water (cp = 4180 j/kg·k) in a 2-shell-passes and 12-tube-passes heat exchanger. the tubes are thin-walled and are made of copper with a diameter of 1.8 cm. the length of each tube pass in the heat exchanger is 3 m, and the overall heat transfer coefficient is 340 w/m2 ·k. water flows through the tubes at a total rate of 0.1 kg/s, and the oil flows through the shell at a rate of 0.2 kg/s. the water and the oil enter at temperatures 18°c and 160°c, respectively. determine the rate of heat transfer in the heat exchanger and the outlet temperatures of the water and the oil. answers: 36.2 kw, 104.6°c, 77.7°c
