The converging-diverging nozzle shown in Fig. P3.22expands and accelerates dry air to supersonic speeds at the exit, where p, = 8 kPa and T, = 240 K. At the throat, p =284 kPa, T; = 665 K, and V = 517 m/s. For steady compressible flow of an ideal gas, estimate (a) the mass flowi n kg/h, (b) the velocity V2, and (c) the Mach number Maz.
