Also Bernoulli Principle / Law
(bɛrnuji)
noun
1. Physics. The principle that in a liquid flowing through a pipe, the pressure difference that accelerates the flow when the bore changes is equal to the product of half the density times the change of the square of the speed, provided friction is negligible.
2. The effect of a change in air pressure depending on the state & position of the vocal folds.
3. The Bernoulli Effect also comes in to play in sailing & aeronautics due the differences in air pressure infront/behind the sail or under/over the wing.
