Natural Fluid System-Grade 8 Science

Link to 9.3 Powerpoint

You will have a test on chapter 9 on Friday, December 17th.  Below is a summary of what the test will be on:
There are both natural and constructed fluid systems.
n  Fluids flow from an area of high pressure to an area of low pressure. (9.1)
n  Pressure in a container of liquid increases with depth. (9.1)
n  Compressed fluids in a closed system exert pressure equally in all directions. (9.2)
n  Hydraulic systems can generate static and dynamic pressure. (9.2)
n  Air can exert force in a pneumatic system. (9.2)
  Natural and constructed fluid systems suffer from similar high- and low-pressure
problems. (9.3)

Definitions:
n  barometer
n  buoyancy
n  buoyant force
n  circulatory system
n  convection
n  diaphragm
n  hydraulic multiplication
n  hydraulic systems
n  hydraulics
n  one atmosphere
n  pneumatic systems
n  pneumatics
n  respiratory system
n   sphygmomanometerions
