Hydraulic inductance

Model of a hydraulic inductance through a massive paddle wheel

The hydraulic inductance (English: hydraulic inductance ) is the resistance of the hydraulic fluid against the acceleration in translational movements in the hydraulic cylinders or pipes or rotational movements in the hydraulic motors . It indicates which pressure difference is required for a change in volume flow : ${\displaystyle \Delta p}$ ${\displaystyle {\ddot {V}}}$

${\displaystyle L_{\mathrm {h} }={\frac {\Delta p}{\ddot {V}}}}$

The name points to the electro-hydraulic analogy , where the inductance describes the relationship between induced voltage and the change in current over time . ${\displaystyle L}$ ${\displaystyle L={\tfrac {U}{dI/dt}}}$ ${\displaystyle U}$ ${\displaystyle I}$
