BERNOULLI'S PRINCIPLE

Daniel Bernoulli, discovered that as the velocity of a fluid increases, its pressure decreases.
How and why does this work, and what does it have to do with the Speed of the car?

A venturi tube is simply a tube which is narrower in the middle than it is at the ends. As the fluid passes over the central part of the tube, more energy is used up, the molecules accelerate. This leaves less energy to exert pressure, and the pressure decreases. This simply means that the pressure at one point is different from the pressure at another point.

The camber of an airfoil causes an increase in the velocity of the air passing over the airfoil. This results in a decrease in the pressure in the stream of air moving over the top of the airfoil

Bernoulli's Equation: The Bernoulli's principle apapplies to any fluid, and since air around the car is a fluid, it applies to air.


GUYS, HOPE THIS PHYSICS LESSON DIDN'T BORE YOU . =)
