What is Bernoulli Equation of Fluid?

Bernoulli's principle is an idea of fluid dynamics. It says that as speed of the fluid increases, pressure decreases. A higher pressure pushes (accelerates) fluid toward lower pressure. So any change in a fluid's speed must be matched by a change in pressure (force).
