Water entering a shell-and-tube heat exchanger at 30°C is to be heated to 70°C by an oil. The oil enters at 100°C and leaves at 70°C. The heat exchanger is arranged with the water making one shell pass and the oil making four tube passes. If the water flow rate is 70 kg/min and the heat exchanger area is 25 m2 , determine: a) the logarithmic temperature difference and b) the overall heat transfer coefficient of this heat exchanger. USE the LMTD method to solve the problem. Write down all your assumptions. Water entering a shell-and-tube heat exchanger at 30°C is to be heated to 70°C by an oil.
