Determine the minimum compressor work input

Question

Problem

1. An air compressor takes air in at the state of the surroundings, 100 kPa, 300 K. The air exits at 400 kPa, 200^oC using 100 kW of power. Determine the minimum compressor work input.

2. The compressor in a refrigerator takes refrigerant R-134a in at 100 kPa, -20?C and compresses it to 1 MPa, 60^oC. With the room at 20^oC, find the minimum compressor 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.
