Air velocity in a vacuum generator
From FestoWiki - english
At what speed does the air flow through a vacuum generator?
The air velocity in a vacuum generator reaches a value greater than Mach 3.
- Mach 1 = speed of sound (340,29 m/s in dry air, at sea level with a temperature of 21°C)
- Mach 2 = twice the speed of sound
- Mach 3 = three times the speed of sound
