FLUID FLOW (TEST FLUID: NO 10 MOTOR OIL)
To find Fluid Outlet Pressure (bar/psi) at a specific fluid flow (lpm/
gpm) and operating air pressure (bar/psi):
1. Locate desired flow along bottom of chart.
2. Follow vertical line up to intersection with selected fluid outlet
pressure curve (black). Follow left to scale and read fluid outlet
pressure.
To find Pump Air Consumption (m#/min or scfm) at a specific fluid
flow (lpm/gpm) and operating air pressure (bar/psi):
1. Locate desired flow along bottom of chart.
2. Follow vertical line up to i ntersection with selected air consump-
tion curve (gray). Follow right to scale and read air consumption.
