Bernoulli's Principle By: Sam C
A great Bernoulli's Principle Video. Youtube.com
Daniel Bernoulli was a Swiss scientist in the eighteenth-century who made the terrific scientific explanation that as the velocity of a fluid is increased, the pressure is decreased. This theory can be shown in many instances, from how an airplances flies using lift, to water's pressure moving through a pipe.

Bernoulli's Principle applies to an airplane, because lower pressure is caused by the increase speed of air on the top of the wing, and the wing is pushed upward due to the increased pressure under the wing.

Daniel Bernoulli was a Swiss scientist who lived during the eighteenth century, and he made an advanced theory of the properties of water flowing through a pipe. He figured out that the greater speed of the flow of a fluid, the less force the water commits perpendicular to the direction of flow. In a simpler form, when the speed of any moving fluid increases, the pressure decreases. This principle is due to the conservation of energy, in which a steady flow has three different kinds of energy: kinetic energy due to motion, gravitational energy due to position, and work associated with pressure.
