Vacuum Pipes - Pressure Loss vs. Air Flow
Sponsored Links
Pressure drop in vacuum pipelines:
Air Flow - scfm - and Pressure Drop - in Hg/100 ft
The diagram is based on initial vacuum pressure 20 in Hg (67% vacuum) and steel pipes schedule 40.
- 1 in Hg = 3.37 kPa
- 1 scfm = 0.472 nl/s
Air Flow - nl/s - and Pressure Drop - kPa/100 m
