A heat exchanger is being used to cool 48,000 lbm/hr of oil from 150°F to 102°F by using 32,000 lbm/hr of water at an inlet temperature of 70°F. The overall heat transfer coefficient is determined to be 145 Btu/hr-ft²-°F. The average heat capacities of the oil and water can be taken as 0.5 Btu/lbm-R and 1.0 Btu/lbm-R, respectively. Determine the heat transfer area required for counter flow and parallel flow configurations.
