The relationship between the velocity and pressure exerted by a moving liquid is described by the Bernoulli's principle: as the velocity of a fluid increases, the pressure exerted by that fluid decreases. Airplanes get a part of their lift by taking advantage of Bernoulli's principle.

Bernoulli's Principle is the principle that allows wings to produce lift and planes and helicopters to fly. There are many factors that can effect the lift produced under this principle, but in order to fully understand how and why things can effect flight one must understand how Bernoulli's principle works.

Bernoulli's principle can be seen most easily through the use of a venturi tube (see Animation or Figure below). The venturi will be discussed again in the unit on propulsion systems, since a venturi is an extremely important part of a carburetor.

[Some suggest to use Bernoulli's principle to explain this effect, while many others find the use of Bernoulli's principle in this manner to be incorrect. Read On!] ... Bernoulli's principle states that an increase in the velocity of any fluid is always accompanied by a decrease in pressure. Air is a fluid. If you can...

This is an important principle involving the movement of a fluid through a pressure difference. ... which is known as Bernoulli's principle. This is very similar to the statement we encountered before for a freely falling object, where the gravitational potential energy plus the kinetic energy was constant (i.

Bernoulli's Principle (top) says that increased air velocity produces decreased pressure. ... Bernoulli's Principle is a physical phenomenon that was named after the Swiss scientist Daniel Bernoulli who lived during the eighteenth century. Bernoulli studied the relationship of the speed of a fluid and pressure.

The air above a wing tends to move faster than the air below it. According to Bernoulli's Principle, slower air has higher pressure than faster air. That means that the air pressure pushing up on the bottom of the wing is greater than the pressure pushing down, so the wing goes up...

This is commonly interpreted as an application of the Bernoulli principle and involves the viscosity of the air and the boundary layer of air at the surface of the ball.
