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.

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
