The damping constant is the ratio between damping force and squeeze velocity. The damping constant can be used to calculate the amplitude of motion around L and the hydrostatic pressure p when the piston is subjected to sinusoidal vibrations F(t).

The impuls is the averaged damping force which can be used to calculate the displacement by impuls loading Fdt. The quotient of the impuls and displacement I/dx of the configurations shown above equals the damping constant C.
