Air volume through orifices
The diagram below indicates the the air leakage or air volume passing through orifices ranging 1/64 - 1/4 inches. For well rounded nozzles, multiply by 0.97. For sharp edged nozzles, multiply by 0.65.
- 1 psig = 6.9 kPa = 0.069 bar
- 1 inch = 25.4 mm
- 1 scfm = 0.472 nl/s
