A 2 shell pass 4 tube pass heat exchanger with an effective heat transfer area of 750 m2 is used to cool reformate that enters at at 83C. The cooling medium is naptha that enters at 30C. The heat capacities of the two streams are 2000 J/kgK (reformate) and 1800 J/kgK (naptha). The mass flow rates of the two streams are the same, at 50,000 kg/h. The overall heat transfer coefficient is 100 W/m2K. Determine the amount of heat transfer that occurs in the exchanger and the outlet temperatures of the two stream
