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