Describe how you can determine the velocity ratio of an Hydraulic machine.

Describe how you can determine the velocity ratio of an Hydraulic machine.

Answers

Consider the diagram below:

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. axd_e=Axd_l,
d_e/d_l= 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.
