Can someone explain this principle to me in as few words as possible (less than 500) whilst retaining quality?
Read Doc Al's post, he gives the key information.rattis said:What is the word equation for this principle?

As the velocity of a flow increases, the pressure drops. The pressure will not go any higher than the pressure of a stagnant (zero velocity) flow.
Bernoulli's Principle is a scientific law that states that as the speed of a fluid increases, its pressure decreases. This principle is named after Swiss mathematician and physicist Daniel Bernoulli, who first described it in the 18th century.
Bernoulli's Principle works by taking into account the conservation of energy in a fluid. As the fluid's speed increases, its kinetic energy also increases, causing a decrease in its potential energy. This decrease in energy results in a decrease in pressure, as described by the equation P + 1/2ρv2 = constant, where P is pressure, ρ is density, and v is velocity.
Bernoulli's Principle can be observed in many everyday situations, such as the lift force on an airplane wing, the flow of air over a curved surface, and the movement of water through a pipe. It is also used in the design of carburetors, atomizers, and other fluid-based systems.
Bernoulli's Principle is a key factor in explaining the phenomenon of lift in aerodynamics. As air flows over the curved surface of an airplane wing, its velocity increases, causing a decrease in pressure according to Bernoulli's Principle. This creates a pressure difference between the top and bottom of the wing, resulting in an upward force (lift) that allows the plane to fly.
While Bernoulli's Principle is a fundamental principle in fluid dynamics, it has some limitations. It assumes an ideal, non-viscous fluid and does not take into account factors such as turbulence or boundary layer effects. Additionally, it is only valid for incompressible fluids, meaning that it cannot be applied to gases such as air at high speeds. However, it is still a useful concept for understanding and predicting fluid behavior in many practical applications.
