Hydraulic Piston Displacement
Use this hydraulic piston displacement tool when you have measured values for bore mm, stroke mm. It applies a transparent mathematical relationship to those values to return an answer in L. Unlike a prediction or recommendation, this is a calculation from your inputs. Uses bore-side volume and ideal cylindrical geometry. Enter a different scenario to see how this particular quantity changes; check the assumptions before using it in a project.
How to use this calculator
- Use exact measurements and consistent units for bore mm, stroke mm.
- Enter each quantity; blank, nonnumeric and out-of-range inputs are not accepted.
- Compare the reported L quantity against your own data and the limitations below.
Formula for Hydraulic Piston Displacement
L = π*bore_mm*bore_mm*stroke_mm/4000000. Inputs are expressed in the units shown by the labels.
- This uses a direct fluid relationship and does not retrieve remote data, forecasts or individual account information.
- Uses bore-side volume and ideal cylindrical geometry.
Worked examples
Worked example — Hydraulic Piston Displacement
Enter Bore mm = 63, Stroke mm = 420.
Apply π*bore_mm*bore_mm*stroke_mm/4000000.
Calculated value: approximately 1.309243 L.
Understanding the result
The example produces about 1.309243 L; this is a mathematical output for the example inputs, not an observed result for your project.
Uses bore-side volume and ideal cylindrical geometry.
Important notes
Uses bore-side volume and ideal cylindrical geometry.
Use values from the same measurement period or physical system. The result is in L and is not a guarantee of capacity, safety, ranking or revenue.
