Cylinder force
- Push force
- — kN
- Push force
- — tf
- Pull force
- — kN
- Pull force
- — tf
A = π·D²/4 · Aann = π·(D²−d²)/4 · F(kN) = p × A / 10000 · tf = kN / 9.81
Cylinder speed
- Extend
- — m/min · — m/s
- Retract
- — m/min · — m/s
Extend m/min = Q × 1000 / A · Retract m/min = Q × 1000 / Aann · m/s = m/min / 60
Pump flow
- Flow
- — L/min
Q (L/min) = V × n × (ηv/100) / 1000
Hydraulic power
- Hydraulic power
- — kW
- Input (motor) power
- — kW · — HP
P(kW) = p × Q / 600 · Input kW = P / (η/100) · HP = kW × 1.341
Hydraulic motor
- Speed
- — rpm
- Torque
- — Nm
n (rpm) = Q × 1000 × (ηv/100) / V · T (Nm) = V × Δp × (ηhm/100) / 62.83
Hose size from flow
Velocity ranges are common rules of thumb; follow the equipment or hose manufacturer's guidance.
- Minimum ID
- — mm
- Next standard size
- —
ID (mm) = 4.607 × √(Q / v)
Tank volume
- Volume
- — L
Litres = L × W × H / 1,000,000
