Problem
1. Air enters an insulated compressor at ambient conditions, 14.7 lbf/ in.2, 70 F, at the rate of 0.1 lbm/s and exits at 400 F. The isentropic efficiency of the compressor is 70%. What is the exit pressure? How much power is required to drive the compressor?
2. A nozzle is required to produce a steady stream of R-134a at 790 ft/s at ambient conditions, 15 lbf/ in.2, 70 F. The isentropic efficiency may be assumed to be 90%. What pressure and temperature are required in the line upstream of the nozzle?
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.
