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 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.
