In a low-speed subsonic wind tunnel with a closed test section, a static pressure tap on the wall of the tunnel test section measures 0.98 atm. The temperature of the air in the test section is 80 ˚F. A Pitot tube is inserted in the middle of the flow in the test section in order to measure the flow velocity. The pressure measured by the Pitot tube is 2,200 psf. Calculate the flow velocity (in KPH) in the test section.
Following manufacture, it is planned to use the biodiesel to power a rocket which uses a de Laval nozzle. The nozzle throat has a cross-sectional area of 5.5 x 10-3 m2. The hot air enters the nozzle at 300 bar(atm) and 77 °C and exits nozzle at 1 bar(atm).
If we have choked flow at the throat, what is the pressure at the throat?
Considering we have choked flow at the throat, what is the flow rate at the exit of the nozzle?
What is the Mach number of an airflow with a velocity of 2000m/s, at 2,000 ft altitude?
