1. Fluid
Something that has the ability to flow
2. Density
mass per unit volume of a substance
3. relative density
ratio of the density of the object to the density of pure water
4. pressure
force acting perpendicular to a unit area
5. barometer
measures atmospheric pressure. a thin strong walled glass tube sealed at one end and open at the other.
6. absolute pressure
the total pressure
7. gauge pressure
any additional pressure over atmospheric pressure
8. manometer
u shaped piece of glass tube that is partially filled with water
9. buoyant force
upward force on submerged objects
10. hydrometer
measure the densities of liquids
11. Blaise pascal
a french mathematician, scientist, and philosopher, discovered one of the most important properties of fluids
12. Archimedes
greatest scientist and mathematician of ancient Greece
13. Bernoulli
Swiss physicist
• Pressure at equal depths in a given fluid is equal
• Pressure is exerted equally in all directions
• Pressure is exerted perpendicular to any surface with which the fluid is in contact
15. Bernoulli's Principle
For steady fluid flow, where the velocity of the fluid is high its pressure is low, and where the velocity is low the pressure is high
16. Archimedes Principle
An object immersed in a fluid experiences a buoyant force that is equal in magnitude to the force of gravity on the displaced fluid
17. Pascal's Principle
Pressure exerted on a contained fluid is transmitted undiminished throughout the fluid acting in all directions and perpendicular to the walls of the container
18. A floating object displaces its own weight of the liquid in which it is floating
19. Normal atmospheric pressure= 760 mm Hg (mercury)
