Engineering Basis
Formulas & Assumptions
Cap-end area: Acap = πD² / 4
Rod-side effective area: Arod-side = π(D² − d²) / 4
Theoretical force: F = P × A
Theoretical speed: v = Q / A
Required flow: Q = v × A
Results are theoretical. Actual force and speed depend on pressure losses, mechanical friction, seal drag, load conditions, circuit design, flow-control behavior and safety factors. Use the calculator for engineering sizing checks, not as an automatic product-selection decision.
