What is exit p and the specific entropy generation

Question

Problem

1. R-410a at -5^oC, 700 kPa is throttled, so it becomes cold at -40^oC. What is exit P and the specific entropy generation?

2. Ammonia is throttled from 1.5 MPa, 35^oC to a pressure of 291 kPa in a refrigerator system. Find the exit temperature and the specific entropy generation in this process.

3. A compressor in a commercial refrigerator receives R-410a at -25^oC and x = 1. The exit is at 1000 kPa, 40^oC. Is this compressor possible?

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.
