A light fuel oil is used in the tube side of a 2-4 shell-and-tube heat exchanger. Water is heated in the shell side from 10°C to 50°C while the oil is cooled from 90°C to 60°C. The overall heat-transfer coefficient is 53 W/(m²-°C). The LMTD correction factor is 0.975.
Calculate the area of the heat exchanger for a total heat transfer rate of 500 kW. ?
