Bernoulli's Principle
The Swiss mathematician and physicist Daniel Bernoulli (1700-1782) discovered the principle that bears his name while conducting experiments concerning an even more fundamental concept: the conservation of energy. This is a law of physics that holds that a system isolated from all outside factors maintains the same total amount of energy, though energy transformations from one form to another take place.

Bernoulli's principle states: As the velocity of a fluid increases, the pressure exerted by that fluid decreases. This principle applies to both liquids and gases.
