Compute the exit temperature and specific entropy generation

Question

Problem

1. A flow of oxygen at 230 K, 5 MPa is throttled to 100 kPa in a steady-flow process. Find the exit temperature and the specific entropy generation using the Redlich-Kwong EOS and ideal gas heat capacity. Notice that this becomes iterative due to the nonlinearity coupling h, P, v, and T.

2. How low should the pressure be so that nitrous oxide (N₂O) gas at 278.6 K can be treated as an ideal gas with 5% accuracy or better?

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.
