Fluids
Physics 202, Lecture 3
1
Pascal’s principle: any pressure change will flow through the entire fluidequally
Physics 202, Lecture 3
2
Archimedes’ principle: vertical pressure differentials provides the force ofbuoyancy
Physics 202, Lecture 3
3
Pressure differentials cause flow; steady flow moves along streamlines ofcurrent
Physics 202, Lecture 3
4
The steady flow of an ideal fluid is both incompressible and non-viscous
Physics 202, Lecture 3
5
Bernoulli’s equation describes the pressure differentials in a ideal fluid thatis flowing
Physics 202, Lecture 3
6
Viscosity is fluid friction; leads to air drag and requires extra pressure forflow
Physics 202, Lecture 3
7
Turbulence driven by speed and size of the object, viscosity and density ofthe fluid
Physics 202, Lecture 3
8
Navier-Stokes equations go beyond Bernoulli, but are very difficult to solve
