**Definition：**

The Bernoulli Equation can be considered to be a statement of **the conservation of energy principle appropriate for flowing fluids**. The qualitative behavior that is usually labeled with the term "Bernoulli effect" is the **lowering of fluid pressure in regions where the flow velocity is increased.**

This lowering of pressure in a constriction of a flow path may seem counter intuitive, but seems less so when you consider pressure to be energy density.** In the high velocity flow through the constriction, kinetic energy must increase at the expense of pressure energy.**
