HYDRAULICS TRAINING MODULE 1
Hydraulic Systems Transmit power from one point to another
Pascal’s Law
Pressure applied on a confined fluid is transmitted undiminished in all directions, and acts with equal force on equal areas, and at right angles to them
Pascal’s Law
This bottle is filled with liquid that is non-compressible
A 10 lb force is applied to a stopper with an area of one square inch Results in 10 lb force on
every square inch of the container wall
If the bottom has an area of 20 sq. in. and each square inch is pushed by a 10 lb of force, the entire bottom receives a 200 lb push
PASCAL’S LAW
• Pressure = Force / Area
Pressure = lb/in2 (psi)
Area = in2
Force = pounds (lb)
INPUT OUTPUT
10 lb 100 lb
Force = Pressure x Area
Purpose of Pumps – To create flow and not pressure.
Pressure is created when the flow is restricted
