Transcribed Image Text:
In a distillery, a plate and frame heat exchanger with a 1-1/U counter flow plate arrangement is being used to cool down a flow of pure ethanol using cold water. The plates are stamped with a 50° chevron pattern. The plate width is 248 mm and the effective heat transfer area of each plate is 0.32 m². The plates have an enlarge- ment factor of 1.25. They are 0.6 mm thick and the plate pitch is 3.2 mm. The etha- nol enters the heat exchanger at a flow rate of 10.3 kg/s at an average temperature of 80°C. The cold water flows at a rate of 9.8 kg/s with an average temperature of 15°C. The diameter of the hot and cold ports on the heat exchanger is 55 mm. The heat exchanger has 116 plates. Determine the total pressure drop of each fluid as it passes through this heat exchanger (kPa).
