Capacity (hydraulics)

The hydraulic capacity is defined as the proportional ratio of volume flow to pressure change .

background

This effect can be illustrated using the example of a car tire: even if the tire is already round and filled with air, it can be further inflated with high air pressure . The volume of air that the tire can hold is exactly the same as the change in pressure multiplied by the tire's capacity.

In the hydraulic is not with air but with oil worked there however is for the purposes of this article, such as air.

formula

${\displaystyle C_{h}={\frac {\dot {V}}{\dot {p}}}={\frac {dV}{dp}}\approx {\frac {\Delta V}{\Delta p}}}$

${\displaystyle \Leftrightarrow \Delta V=C_{h}\Delta p}$.
