Question

Hello What is the Bernoulli equation

Answer 1

Bernoulli equation is a mathematical expression that describes how pressure of fluid depends on its velocity. Also, we can say that this is a law of conservation of energy for liquids. It looks like this:

$$\frac{\rho v^2}{2}+\rho gh+p=\text{const},$$

where

$\rho$ - density

$v$ - velocity

h - height of water pillar

$g$ - acceleration due to gravity

$p$ - pressure
