Problem
1. A flow of 1.8 kg/s steam at 400 kPa, 400oC is mixed with 3.2 kg/s oxygen at 400 kPa, 400 K in a steady-flow mixing chamber without any heat transfer. Find the exit temperature and the rate of entropy generation.
2. Carbon dioxide gas at 320 K is mixed with nitrogen at 280 K in an insulated mixing chamber. Both flows are at 100 kPa, and the mass ratio of carbon dioxide to nitrogen is 2:1. Find the exit temperature and the total entropy generation per kilogram of the exit mixture.
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.
