35.1.2.2. Hydraulic Force

Hydraulic Force to Plunger

The Hydraulic Force can be calculated as follows:

\({{F}_{plunger\_hydraulic}}=\Delta p\times {{S}_{p}}\)

where,

\({{S}_{p}}\) is the area of plunger.

Hydraulic Force to Check Ball

The Hydraulic Force can be calculated as follows:

\({{F}_{ball\_hydraulic}}=\Delta p\times {{S}_{B}}-{{\eta }_{B}}\Delta v\)

where,

\({{S}_{B}}\) is the area of check ball

\({{\eta }_{B}}\) is the damping coefficient of check ball in the oil
