The air with constant properties in a steady adiabatic flow enters a system at a pressure of 10 bars and 500K with a velocity of 100 m/s and leaves at 2 bars and 330 K with a velocity of 50 m/s
a) Find the reversible amount of of work per unit mass
b) Find the isentropic efficiency for the process as air goes through the system
c) sketch both reversible and actual processes onT-s or h-s diagram
d) Find the change in entropy per unit mass as air goes through the system
