Hydraulic Cylinder Force
Calculate push and pull force of a double-acting hydraulic cylinder based on bore, rod diameter and …
F [N] = A [cm²] × p [bar] × 10
Cylinder Volume, Speed & Flow
Calculate cylinder volumes, required pump flow for a target speed, or resulting speed from a given f…
Q [l/min] = A [cm²] × v [m/s] × 600 ↔ v [m/s] = Q / (A × 600)
Hydraulic Power Unit Sizing
Calculate hydraulic power, motor power requirement and pump speed based on system pressure, flow and…
P_hyd [kW] = p [bar] × Q [l/min] / 600 | P_motor = P_hyd / (η_vol × η_mech)
Telescopic Cylinder Forces
Calculate force and volume for each stage of a hydraulic telescopic cylinder with up to 4 stages.…
F_stage [N] = π/4 × D_stage² [cm²] × p [bar] × 10
Pump Displacement Calculation
Calculate the geometric displacement of a gear pump or axial piston pump from its physical dimension…
Gear: Vs = π × m × z × b × h [cm³] | Axial piston: Vs = z × π/4 × d² × 2r × tan(α) [cm³]
Pressure Unit Converter
Convert hydraulic pressure between bar, PSI, MPa, kPa and kgf/cm².…
1 bar = 100 kPa = 0.1 MPa = 14.504 PSI = 1.0197 kgf/cm²
Hydraulic Pipe Flow & Pressure Loss
Calculate pressure loss in a hydraulic pipe using the Hagen-Poiseuille equation for laminar flow and…
Laminar: ΔP = (128 × η × L × Q) / (π × D⁴) | Turbulent: ΔP = f × L/D × ρv²/2
Hydraulic Accumulator Sizing
Calculate the required accumulator volume for energy storage, pulsation damping or emergency operati…
V_acc = V_useful × (P_max/P_min)^(1/n) / (1 − (P_min/P_max)^(1/n)) [n=1.4 adiabatic]
