Vacuum Pipes - Pressure Loss vs. Air Flow

Calculate pressure drops in vacuum pipe lines.

Pressure drop in vacuum pipelines:

Air Flow - scfm - and Pressure Drop - in Hg/100 ft

Vacuum pipe line - pressure drop diagram - inHg and cfm

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

Vacuum pipe line - pressure drop diagram - l/s and kPa
