Pressure drop in vacuum pipelines are indicated in the diagrams below.

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

vacuum pipe line pressure drop diagram

The diagram is based on initial vacuum pressure 20 in Hg (67%) 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
