Pascal’s and Bernoulli’s Principles

2. Pascal’s Principle
When a force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid.
Ex. Squeezing a tube of toothpaste.

3. Hydraulics Hydraulic systems are based on Pascal’s principle.
Squeezing liquid in one area creates a pressure in another area.
EX. Car brakes

4. Bernoulli’s Principle
As the speed of a moving fluid increases, its pressure decreases.
This is how airplanes fly.

6. Uses of Bernoulli’s Principle
Smoke rises in the chimney as air blows across the top of the chimney creating low pressure
Frisbee’s can fly
