Physics 202 Lecture 3

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

Archimedes’ principle: vertical pressure differentials provides the force of buoyancy

Page 4: Fluids Physics 202 Lecture 3. Pascal’s principle: any pressure change will flow through the entire fluid equally

Pressure differentials cause flow; steady flow moves along streamlines of current

Page 5: Fluids Physics 202 Lecture 3. Pascal’s principle: any pressure change will flow through the entire fluid equally

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

Page 6: Fluids Physics 202 Lecture 3. Pascal’s principle: any pressure change will flow through the entire fluid equally

Bernoulli's equation describes the pressure differentials in a ideal fluid that is flowing

Page 7: Fluids Physics 202 Lecture 3. Pascal’s principle: any pressure change will flow through the entire fluid equally

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

Page 8: Fluids Physics 202 Lecture 3. Pascal’s principle: any pressure change will flow through the entire fluid equally

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

Page 9: Fluids Physics 202 Lecture 3. Pascal’s principle: any pressure change will flow through the entire fluid equally

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