Bernoulli's principle. The above answer is wrong. Its Pascal's Principle :)
Bernoulli's Principle
Pascal's Principe is the rule that when force is applied to a confined fluid the increase in pressure is transmitted equally to all parts of the fluid.Bernoulli's principle is the rule that a stream of fast moving fluid exerts less pressure than the surrounding fluid
An example of Bernoulli's principle is an Airplane. Your Welcome[:
A Bernoulli effect is an occurrence of Bernoulli's principle in a flowing fluid.
Bernoulli's Principle uses Pascal's Law to relate the final and initial states of an ideal liquid. Pascal's Law says that a change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid, meaning that for an ideal fluid (Δρ = 0): ΔP = ρgΔh where ρ is fluid density, g is gravitational pull and h is height pf fluid above measurement. Bernoulli's Principle states that for an ideal fluid, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy: 0.5ρv2 +ρgh + P = constant Where v = velocity of the fluid. If the fluid is stationary, v = 0. Taking the derivative of this: Δ(ρgh) + ΔP = 0 Again, assuming ideality, ρgΔh + ΔP = 0 If we raise the fluid, the pressure will drop, meaning that we can rearrange the equation to: ΔP = ρgΔh

Swiss mathematician and physicist Daniel Bernoulli discovered what is known as the Bernoulli effect, or the Bernoulli Principle.
