### Fluid Power

What is Fluid Power?
• Fluid power is energy transmitted and controlled by means of a pressurized fluid, either liquid or gas.
• Hydraulics uses pressurized liquid, such as oil or water.
• Pneumatics uses compressed air or other neutral gases.
• Fluid power can be effectively combined with other technologies through the use of sensors, transducers, and microprocessors.
How Does Fluid Power Work?

Pascal\'s Law expresses the central concept of fluid power:

"Pressure exerted by a confined fluid acts undiminished equally in all directions."

An Example
• An input force of 10 pounds on a 1-square-inch piston develops a pressure of 10 pounds per square inch (psi) throughout the container.
• This pressure will allow a 10-square-inch piston to support a 100-pound weight.
• The forces are proportional to the piston areas.
• Multiplication and variation of force
• Easy, accurate control
• Multi-function control
• High horsepower, low weight
• Low speed torque
• Constant force or torque
• Safety in hazardous environments
