Problem 5(20 points)
A heat exchanger is being used to transfer heat between water and a ethanol. The ethanol enters the heat exchanger at 4m3h with a temperature of 70 C . The water enters the heat exchanger at 3m3h at a temperature of 10C. The UA product of the heat exchanger is found to be 2800kJhK. Determine the heat transfer rate between the fluids for a parallel-flow heat exchanger using the e-NTU method.
