KEY FLUID PRESSURE AND FLOW
SCFM AIR CONSUMPTION
100 psi air
(7 bar)
Example of Finding Pump Air Consumption and Air Pressure at a Specific Fluid Deliv-
ery and Discharge Head: To supply 3 gpm (11.4 liters) fluid flow (horizontal scale) at 50 psi
(3.5 bar) discharge head pressure (vertical scale) requires 3 scfm (.084 m
#/min) air con-
sumption at 70 psi (4.9 bar) inlet air pressure.
