Topic 8: Fluid Systems

2. Hydraulics Is the study of pressure in liquids.
Hydraulic Systems - Devices that send forces through a liquid to move something else, due to pressure.

3. Hydraulic Systems
Liquids transmit a force in all directions so to make a hydraulic system you need something to provide a force (the pump), strong container with no leaks, and valves which direct/control liquid flow.

4. Pneumatic Systems
Are like hydraulic systems, but use gases instead of liquids. They are used differently because of their compressive nature.
Instead of a pump to provide force, pneumatic systems use a compressor to supply the force and build up the pressure.

5. Applications of Hydraulics and Pneumatics
- Circulatory System, water hose, garage lift.
Pneumatics
- Respiratory System, dentist drill, carbonated drinks, barber stool
