Air at -55 F, 4 psia, and M=2.5 enters a constant area isentropic process and leaves the isentropic process at M=0.2 Assuming a calorically perfect, ideal gas determine.
A. The pressure (psia) and temperature (R) of the leaving air.
B. The density (lbm/ft^3) of the entering air and the density (lbm/ft^3) of the leaving air.
