  1. Science 8 - Unit A - Mix and Flow of Matter 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 • Hydraulics • - Circulatory System, water hose, garage lift. • Pneumatics • - Respiratory System, dentist drill, carbonated drinks, barber stool
