1 Topic: Fluids PHYSICS 231
2 Key Concepts Density, Volume, Mass density as material property Pressure units, how to measure, direction Hydrostatic pressure in liquid on earth Buoyancy and Archimedes Principle How to calculate buoyancy force Floating and sinking Continuity equation for incompressible liquid Sets fluid speed for a given flow Bernoulli equation for flowing fluid Pressure changes drive velocity changes and compensate gravity to maintain flow. 3/28/11 Physics 231 Spring
3 Key Equations Note that these are only useful once you understood the concepts and can derive equations that apply to a specific problem Pressure: p=f/a Hydrostatic pressure Buoyancy force: (upward) Bernoulli equation: p = p 0 + ρgd F B = ρ f V f g p ρv 2 + ρgh = constant 3/28/11 Physics 231 Spring

25 Clicker Quiz A princess sits in a boat on a pond. She throws a golden ball into the water, which sinks to the bottom. Water level: A: rises B: stays the same C: decreases Reason: a floating golden ball in the boat displaces more volume (its weight worth of water) than a sinking one (its volume) 3/28/11 Physics 231 Spring
