1

Pascal’s principle: any pressure change will flow through the entire fluidequally


2

Archimedes’ principle: vertical pressure differentials provides the force ofbuoyancy


3

Pressure differentials cause flow; steady flow moves along streamlines ofcurrent


4

The steady flow of an ideal fluid is both incompressible and non-viscous


5

Bernoulli’s equation describes the pressure differentials in a ideal fluid thatis flowing


6

Viscosity is fluid friction; leads to air drag and requires extra pressure forflow


7

Turbulence driven by speed and size of the object, viscosity and density ofthe fluid


8

Navier-Stokes equations go beyond Bernoulli, but are very difficult to solve
