| The consumption of compressed air by nozzles of different shapes can vary greatly and depends on various factors :
- Diameter of the nozzle.
The larger the nozzle, the greater the consumption.
- Operating pressure of nozzle.
The higher the operating pressure, the greater the consumption.
- Shape of nozzle.
A simple, cylindrical through-hole consumes much less compressed air than a conical or Laval-nozzle (expansion nozzle).
- Surface quality of aperture .
If the quality of the aperture is very good (surface very smooth, no grooves and unevenness), more compressed air can flow through.
- Spraying or blowing.
The consumption of compressed air rises if the air is being used as a medium for paint, sand, or the like.
