Problem
A counter flowing heat exchanger cools air at 600 K, 400 kPa to 320 K using a supply of water at 20?C, 200 kPa. The water flow rate is 0.1 kg/s and the air flow rate is 1 kg/s. Assume this can be done in a reversible process by the use of distributed heat engines between the lines and neglect kinetic energy changes. Find the water exit temperature and the power out of the heat engine(s).
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.
