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.

FLUID FLOW––gpm (lpm)

To calculate Pressure Head in feet at a specific fluid outlet pressure (psi):

pressure head, feet = (psi * 2.31) / specific gravity of fluid

To calculate Pressure Head in meters at a specific fluid outlet pressure (MPa):

pressure head, meters = (MPa * 102) / specific gravity of fluid

To calculate Pressure Head in meters at a specific fluid outlet pressure (bar):

pressure head, meters = (bar * 10.2) / specific gravity of fluid
