Water entering a shell and tube heat exchanger at 350C is to be heated to 75 oC by an oil. The oil enters at 110 oC and leaves at 75 >C, the heat exchanger is arranged for counter flow with the water making one shell pass and the oil making two tube passes. If the vater flow rate is 68 kg/min and the overall heat transfer coefficient is 320 W/m2 K, calculate the required .heat exchanger area
