1. Air at po 5 1.4 bar, To 5 280 K expands isentropically through a converging nozzle and discharges to the atmosphere at 1 bar. The exit plane area is 0.0013 m2.
(a) Determine the mass flow rate, in kg/s.
(b) If the supply region pressure, po, were increased to 2 bar, what would be the mass flow rate, in kg/s?
2. Air enters a nozzle operating at steady state at 45 lbf/in.2, 8008R, with a velocity of 480 ft/s, and expands isentropically to an exit velocity of 1500 ft/s. Determine
(a) the exit pressure, in lbf/in.2
(b) the ratio of the exit area to the inlet area.
(c) whether the nozzle is diverging only, converging only, or converging-diverging in cross section.

Determine the back pressure
: A converging-diverging nozzle operates at steady state. Air as an ideal gas with k 5 1.4 enters the nozzle at 500 K, 6 bar, and a Mach number of 0.3. The air flows isentropically to the exit plane, where a normal shock stands. The temperature just..
