Problem
1. Friction in a pipe flow causes a slight pressure decrease and a slight temperature increase. How does that affect entropy?
2. To increase the work out of a turbine for given inlet and exit pressures, how should the inlet state be changed?
3. An irreversible adiabatic flow of liquid water in a pump has a higher exit P. Is the exit T higher or lower?
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.
