Air flows through the converging-diverging nozzle. The conditions at the inlet side are at standard atmospheric conditions, while the density and the temperature at station B is 0.060 lbm/ft3 and 30.5 degree Fahrenheit. Also, the density at station C is 0.050 lbm/ft3, with the velocity at station A recorded to be at 380 ft/s. Determine the following, assuming ideal gas conditions and isentropic process:
Draw a diagram of the converging-diverging nozzle, where the diameter at station
A=5 in, B=2 in, and the diameter at station C=6 in.
The answer addresses the mass flow of air, velocity and pressure of varying stations, and the changes in energy.
