In fluid dynamics, Bernoulli’s principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid’s potential energy. The principle is named after Daniel Bernoulli who published it in his book Hydrodynamica in 1738.

**Bernoulli’s Equation Formula**

Following is the formula of Bernoulli’s equation:

P+12ρv^{2}+ρgh=constant

Where,

- P is the pressure
- v is the velocity of the fluid
- ρ is the density of the fluid
- h, is the height of the pipe from which the fluid is flowing.
