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/in 2 (psi) Area = in 2 Force = pounds (lb)

INPUTOUTPUT 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 O Psi
