Problem
A condenser is maintained at 60oC by cooling it with atmospheric air coming in at 20oC and leaving at 35oC. The condenser must reject 25 MW from the water to the air. Find the flow rate of air and the second-law efficiency of the heat exchanger.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
