Understanding Fluid Dynamics: Density, Pressure, and Buoyancy Explained

Explore the fascinating concepts of density, pressure, and buoyancy in fluids. Discover why boats float even though iron is denser than water, thanks to buoyant force. Learn about atmospheric pressure, Pascal’s Principle, and how forces act in all directions within fluids. Delve into famous theories, including Archimedes' principle and Bernoulli’s principle, which explains how airplanes stay aloft. This comprehensive overview will enhance your understanding of fluid dynamics in a fun way!

Presentation Transcript

  1. Fluids

  2. 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…

  3. Pressure • Pressure, Force, and Area • ALL DIRECTIONS IN FLUIDS • P=ρgh…Why?

  4. Atmospheric Pressure • Would a straw work in outer space? • Gauge and Absolute pressure

  5. Pascal’s Principle

  6. Buoyancy • Check this out! • What is buoyant force? • Example 10-7

  7. Archimedes • Weight of water displaced=Buoyant Force! • The quandary of a King • Eureka! (I’ve found it) • How it works

  8. Density vs. Buoyancy • Displace more water with the same mass… Get more Buoyant Force!

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