Cylinder speed calculator
Extend/retract speed, stroke time and air or oil volume from bore, rod, stroke, working pressure and supply flow.
Ideal incompressible or isothermal fill. Valves, hose ID, cushioning and load change real time — size from the datasheet.

Formulas
v = Q / A (air: Q_work = Q_ANR / (P+1))
t = L / v V_cycle = (A + a) · L · (P+1)
