Multi-Cylinders conduits calculation

Cylinders conduits flow

Cylinder’s flow

These calculations can help you to figure-out conduits (hoses, pipes or tubes) parameters (ID sizes, piston speed, flow velocity and cylinder’s force) for any qty of cylinders connected in parallel circuit.

Calculations Notes:

  • The recommended flow velocity in conduits you can find at the article Recommended flow velocity.
  • The assumption: if you use more than 1 cylinder in calculations, all cylinders have the same parameters (bore/rod diameters, stroke and friction)
  • The assumption: Pressure and Return lines conduits (flow source – flow divider and flow divider – tank) have the same ID size.
  • The assumption: the conduits between flow divider and cylinders have the same ID size.

Recommended flow velocity

These values I use for my calculations when I need to compare flow velocity with recommended min and max values. I took these data from different sources: recommendations in technical manuals of Parker, Gates, Eaton and other hose and tubes suppliers.

These are average values from my collection of all supplier recommendations.
