What Is Fluid Power
• Energy controlled by the use of
pressurized fluid (liquid or
gas).
• This can relate to both
hydraulics and pneumatics.
Hydraulics
• Uses pressurized liquid
• Many types of liquid can
be used
• Hydraulics can be found
in many places.
• Use this website to find
two types of liquid and 5
uses for hydraulics.

Pneumatics
• Uses compressed air or
gas to transfer energy.
• This also uses many types
of gasses
• There are also many uses
of pneumatic technology.
• Use this website below to
find 2 types of gases and 4
uses of pneumatics

How Does Fluid Power Work?
• Pascal’s Law:
– “Pressure exerted by a confined fluid acts
undiminished equally in all directions”
• Who is Pascal? Find 5 facts about him here:

html
– In other words, no pressure is lost when
transferring it through fluid power
technologies.
What Are Some Advantages?
•
•
•
•
Easy to control/Easy power transfer
Always a constant force
High amount of force for it’s low weight.
Quick response
What are some Disadvantages?
• Possible fire/explosive hazard for some
liquids
• Must not contain any outside debris
• Difficult to clean up
Find and explain how hydraulic
pressure is used in everyday
objects.
