Consider the diagram below:
42420191000.png
When the effort is applied as shown, the volume of the liquid leaving the effort arm is the same as the volume of the liquid entering the load arm;
i.e. axde=Axdl,
de/dl= A/a
Therefore, the velocity ratio of a hydraulic system is the ratio of the area of the load piston to the area of the effort piston. If the pistons are circular then;
V.R=area of load piston/area of effort piston =pR2/pr2
V.R=R2/r2, where R- is the radius of the load piston and r- is the radius of the effort piston.
