Question 3: Water flowing at the rate of 1.1 kg/s in a 2-4 shell-and-tube heat exchanger is heated from 50 °C to 75 °C by an oil having a heat capacity of 1.9 kJ/kg.K. The oil enters the heat exchanger at 125 °C and leaves at 90 °C. Calculate the area of the heat exchanger if the overall heat-transfer coefficient is 250 W/m².K.
