SUMMARY
The maximum air velocity achievable in ambient conditions is determined by the design of the nozzle used. A choked converging/diverging nozzle allows air to reach sonic velocity at the throat, and subsequently accelerates the air to supersonic speeds beyond the throat. This principle is utilized in supersonic wind tunnels, which effectively demonstrate the capability of achieving velocities greater than the speed of sound in ambient conditions.
