To find the fluid pressure (psi/bar/MPa) at a specific
fluid flow (gpm/lpm) and percentage of maximum
force:
1. Locate the desired fluid flow in the scale at the
bottom of the chart.
2. Follow the vertical line up to the intersection with
the selected percentage of maximum force (see
Key below).
the Key Key
3. Follow left to the vertical scale to read the fluid
outlet pressure.
