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.
