  1. Pressure In confined Fluids Hydraulic and Pneumatic Systems

  2. What is a confined fluid? • They are fluids in a closed system. • The fluid can move around with in the system but can not enter or leave the system. Can you think of any other examples of confined fluids? The blood inside your body is a confined fluid Water in an open cup is not a confined fluid

  3. Confined Fluids are Useful • A small downward force on a piston in a closed container causes pressure to be exerted in all directions. • This pressure is the same in all directions so the force can build and be transmitted to every part of a fluid

  4. Pascal’s Principle- when a confined fluid is subjected to an externally applied pressure, the pressure at all points within the fluid increase by the applied amount Blaise Pascal: Invented the hydraulic press and the syringe

  5. Two Types of Confined Fluid Systems • Hydraulic system: is a confined pressurized system that uses moveable liquids • Pneumatic system: is a confined pressurized system that used moving air or other gasses such as carbon dioxide. Examples: read section 5.8 in textbook Hydraulic system: Pneumatic system:

  6. Effects when a force is applied to a gas or a liquid. • By increasing the pressure on a gas the particles can be pushed close enough together that the gas will change to a liquid Example? • Propane • Oxygen for oxygen masks in an airplane
