FLUID FLOW – gpm (lpm)<br />
To find Fluid Outlet Pressure (psi/MPa/bar) at a specific fluid flow (gpm/lpm) and operating air pressure (psi/MPa/bar):<br />
1. Locate fluid flow rate along bottom of chart.<br />
2. Follow vertical line up to intersection with selected fluid outlet pressure curve.<br />
3. Follow left to scale to read fluid outlet pressure.<br />
