#### Bernoulli’s principle equation

## What does Bernoulli’s principle state?

Explore the Bernoulli Principle, which states that the speed of a fluid (air, in this case) determines the amount of pressure that a fluid can exert.

## Why we use Bernoulli’s equation?

The Bernoulli equation is an important expression relating pressure, height and velocity of a fluid at one point along its flow. Because the Bernoulli equation is equal to a constant at all points along a streamline, we can equate two points on a streamline.

## What does Bernoulli’s equation tell us?

The Bernoulli Equation can be considered to be a statement of the conservation of energy principle appropriate for flowing fluids. The qualitative behavior that is usually labeled with the term “Bernoulli effect” is the lowering of fluid pressure in regions where the flow velocity is increased.

## Where is Bernoulli’s principle used?

Bernoulli’s principle can be applied to many everyday situations. For example, this principle explains why airplane wings are curved along the top and why ships have to steer away from each other as they pass. The pressure above the wing is lower than below it, providing lift from underneath the wing.

## What is Bernoulli’s Theorem and its application?

Bernoulli’s theorem is the principle of energy conservation for ideal fluids in steady, or streamline, flow and is the basis for many engineering applications.

## What are four applications of Bernoulli’s principle?

List four applications of Bernoulli’s principle. Airplane wings, atomizers, chimneys and flying discs. Why does the air pressure above an airplane wing differ from the pressure below it?
