sci.hydraulic-cylinder-force-speed Calculator
Calculates hydraulic cylinder force F = P×A and extension speed v = Q/A from pressure and flow rate for a linear actuator. A 100 mm bore cylinder at 200 bar generates 157 kN force — cylinder speed at 30 L/min = 63 mm/s.
Inputs
P Bar
Force per unit area (Pa). Atmospheric pressure at sea level: 101,325 Pa. Check whether gauge or absolute pressure is required.
D Bore Mm
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
D Rod Mm
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
Q L Min
Volume of fluid per unit time. Used to size pipes, pumps, and ducts.
Results
extension force F_ext (kN)
The tensile force or stress — the pulling force that stretches the material. Must stay below the material's tensile strength.
retraction force F_ret (kN)
Sample size or count used in the calculation.
extension speed v_ext (mm/s)
The tensile force or stress — the pulling force that stretches the material. Must stay below the material's tensile strength.
retraction speed v_ret (mm/s)
The computed rate of movement or processing.
F = P·A; v = Q/A
Reference formula or conversion factor shown for context.
area ratio (regenerative)
The proportional relationship between two quantities.
