Frequently asked questions

How is hydraulic cylinder force calculated?

Force equals Pressure multiplied by Area (F = P x A). For the push stroke, use the full piston area. For the pull stroke, subtract the rod area from the piston area.

What is the Reynolds Number used for?

The Reynolds Number (Re) is a dimensionless value used to predict whether fluid flow will be laminar (smooth) or turbulent (chaotic), which is critical for calculating pressure drop.

How do I size a hydraulic pump?

Sizing depends on the required flow (LPM or GPM) and the system pressure. Power (kW) = [Flow (LPM) x Pressure (bar)] / 600. Our tool automates this with efficiency corrections.
