# What Is Bernoulli’s Principle & applications like airplane wing and sails

**Bernoulli’s principle **is named for Daniel Bernoulli, who presented it in 1738, and it concerns the relationship between pressure and flow speed in fluids.

In its simplest form, **Bernoulli’s principle states that increasing flow speed in fluids corresponds to decreasing pressure, and vice versa.**

**Application of Bernoulli’s Principle — Airplane wings and Sails**

An important example is in aviation. The **airplane wing** is a beautiful example of Bernoulli’s principle in action.

The wing is tilted upward at a small angle and the upper surface is longer, causing air to flow faster over it.

That means a higher flow speed on the top of the wing than on the bottom.

The pressure on top of the wing is therefore reduced, creating a net upward force or lift.
