The Bernoulli Effect
BY: HANNAH ARNER
History of the Bernoulli Effect

In 1738, a brilliant mathematician by the name of Daniel
Bernoulli came up with a theory.

His ideas have been named Bernoulli’s principle, the Bernoulli
effect, and Bernoulli’s law.

Daniel Bernoulli published the book Hydrodynamica, where
he presented his theory.
The Bernoulli Principle…what is it?

Officially, Bernoulli’s Principle is a statement of relationship
between flow speed and pressure in a fluid system

Bernoulli's principle states that fluids in an area moving faster
than the surrounding area possess less pressure. Fastermoving fluid  lower pressure than the rest of its surroundings.

**Important note** Fluids include liquids and gasses. Air is a
gas and as such is classified as a fluid.
