Question

The converging–diverging nozzle shown in Fig. P3.22
expands and accelerates dry air to supersonic speeds at the
exit, where p ₂ = 8 kPa and T ₂ = 240 K. At the throat, p ₁=
284 kPa, T ₁ = 665 K, and V₁ = 517 m/s. For steady
compressible fl ow of an ideal gas, estimate ( a ) the mass fl ow
in kg/h, ( b ) the velocity V₂ , and ( c ) the Mach number Ma ₂ .
