Heat exchange between oil and water. water is flowing at the rate of 1.13 kg/s in a 1-2 shell-and-tube heat exchanger and is heated from 45°c to 85°c by an oil having a heat capacity of 1.95 kj/kg. k. the oil enters at 120°c and leaves at 85°c. calculate the area of the exchanger if the overall heat-transfer coefficient is 300 w/m2.k.
