Find the compressor specific work and entropy generation

Question

Problem

1. Liquid water enters a pump at 15^oC, 100 kPa and exits at a pressure of 5 MPa. If the isentropic efficiency of the pump is 75%, determine the enthalpy (steam table reference) of the water at the pump exit.

2. Ammonia is brought from saturated vapor at 300 kPa to 1400 kPa, 140^oC in a steady-flow adiabatic compressor. Find the compressor specific work, entropy generation, and its isentropic efficiency.

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.
