Problem
1. A steady flow of 0.1 kmol/s carbon dioxide at 1000 K in one line is mixed with 0.2 kmol/s nitrogen at 400 K in another line, both at 100 kPa. The exit mixture at 100 kPa is compressed by a reversible adiabatic compressor to 500 kPa. Use constant heat capacity to find the mixing chamber's exit temperature and the needed compressor power.
2. A mixture of 2 kg oxygen and 2 kg argon is in an insulated piston/cylinder arrangement at 100 kPa, 300 K. The piston now compresses the mixture to half of its initial volume. Find the final pressure, temperature, and the piston work.
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.
