To find Fluid Outlet Pressure (psi/MPa/bar) at a specific fluid flow
(lpm/gpm) and operating hydraulic pressure (psi/MPa/bar):
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 to read fluid outlet
pressure.

To find Motor Hydraulic Oil Consumption (lpm or gpm) at a specific
fluid flow (lpm or gpm):
1. Locate desired flow along bottom of chart.
2. Read vertical line up to intersection with hydraulic oil consumption
curve (dashes). Follow left to scale to read hydraulic oil consump-
tion.
