A concentric tube heat exchanger is used to cool a solution of ethyl alcohol (Cp = 3810 J/kg-K) from 65.6 degrees C to 39.4 degrees C using water flowing at 6.30 kg/s at a temperature of 10 degrees C. Assume that the overall heat transfer coefficient is 568 W/m2-K. Use Cp = 4187 J/kg-K for water. A. What is the exit temperature of the water?
B. Can you use a parallel flow or counterflow heat exchanger here? Explain.
C. Calculate the rate of heat flow from the alcohol solution to the water.
D. Calculate the required heat exchanger area for a parallel flow configuration.
E. Calculate the required heat exchanger area for a counter flow configuration. What happens when you try to do this? What is the solution?
