Transcribed Image Text:Problem 14.1
A steady flow compressor handles 113.3 m³/min
of nitrogen measured at intake where p, = 97.22
kPaa and t = 26.7°C. Discharge is at 310.27
kPaa. The change of kinetic energy is negligible.
For each of the following cases, determine the
temperature t, and the work if the process is
(a) an isentropic, (b) an internally reversible
polytropic with n = 1.34, (c) an irreversible
adiabatic with a compressor efficiency of
n. = 80%, (d) an isothermal. Solve this problem
from the view point of energy diagrams. Does
- V dp represent anything asked for?
