Mach number atmospheric discharge

Example 7 Flow through Frictionless Nozzle Air at p0 and temperature T0 = 293 K discharges through a frictionless nozzle to atmospheric pressure. Compute the discharge mass flux G, the pressure, temperature, Mach number, and velocity at the exit. Consider two cases (l)p0 = 7 X 105 Pa absolute, and (2) p0 — 1-5 x 10s Pa absolute.
