Asingle pass cross-flow heat exchanger is used to cool jacket water (cp = 1.0 btu/lbm · °f) with inlet temperature of 100°f. both air flow and water flow are unmixed. if the water and air mass flow rates are 95,000 lbm/h and 450,000 lbm/hr, respectively, determine the log mean temperature difference for this heat exchanger.
