Presentation Transcript

### Fluids

Density
• ρ (rho), mass, and volume
• Density and Specific Gravity

The density of Iron is greater than that of water…so why do (most) boats float? See Buoyancy…

Pressure
• Pressure, Force, and Area
• ALL DIRECTIONS IN FLUIDS
• P=ρgh…Why?
Atmospheric Pressure
• Would a straw work in outer space?
• Gauge and Absolute pressure
Buoyancy
• Check this out!
• What is buoyant force?
• Example 10-7
Archimedes
• Weight of water displaced=Buoyant Force!
• The quandary of a King
• Eureka! (I’ve found it)
• How it works
Density vs. Buoyancy
• Displace more water with the same mass…

Get more Buoyant Force!

Fluid Dynamics
• What is Mr. Weasly’s aspiration in life?
• Find out how airplanes stay up! (Harry Potter reference)
• Bernoulli’s Principle!
• Curve balls?
