Bernoulli’s Magic Trick

by Garcia, Ricael

In fluid dynamic, Bernoulli’s principle states that for an In-viscid flow, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid’s potential energy.

Bernoulli’s principle can be applied to various types of fluid flow, resulting in what is loosely denoted as Bernoulli’s equation. In fact, there are different forms of the Bernoulli equation for different types of flow. The simple form of Bernoulli’s principle is valid for in-compressible flows (e.g. most liquid flows) and also for compressible flows (e.g.gases) moving at low Mach numbers. More advanced forms may in some cases be applied to compressible flows at higher Mach numbers (see the derivations of the Bernoulli equation)
