To find Fluid Outlet Pressure

 (psi/MPa/bar) at a specific fluid flow (gpm/lpm) and operating air pressure

(psi/MPa/bar):

1.

Locate fluid flow rate along bottom of chart.

2.

Follow vertical line up to intersection with selected fluid outlet pressure curve.

3.

Follow left to scale to read fluid outlet pressure.
