Pressure+on+Moving+Fluids

== "A fluid at rest exerts pressure—what Bernoulli called "static pressure"—on its container. As the fluid begins to move, however, a portion of the static pressure—proportional to the speed of the fluid—is converted to what Bernoulli called dynamic pressure, or the pressure of movement. In a cylindrical pipe, static pressure is exerted perpendicular to the surface of the container, whereas dynamic pressure is parallel to it." - Findarticles.com

"The potential energy of a moving fluid is more useful in applications like the Bernoulli equation when is expressed as potential energy per unit volume."

"The energy density of a fluid can be expressed in terms of this potential energy density along with kinetic energy density and fluid pressure." -Hyperphysics.com



// Example of Moving Fluid Pressure //
In other words, the more room the fluid has to flow, the more pressure the fluid has. The less room a fluid has to flow, the less pressure it has, as shown in the pictures above and below. The pressure from the large container in this picture is so large it causes enough force to shoot the fluid up from the opening. Though if the container was smaller in size it wouldn't have the same result.
