A supersonic converging-diverging nozzle is to be designed to be attached to a standard machine shop air supply having isentropic stagnation conditions of 100. psia and 70.0°F. The throat of the nozzle is to have a diameter of 0.250 in, and the nozzle exhausts into the atmosphere at 14.7 psia. For an isentropic nozzle, determine
a. The exit Mach number.
b. The exit temperature.
c. The mass flow rate of air through the nozzle.
d. The exit diameter of the diverging section.
