The Venturi effect is the creation of a partial vacuum when the flow of a fluid is restricted, increasing its speed of flow. Thus, a pipe with a fluid flowing through it which narrows at one point before widening again d... More » Science Physics

The Bernoulli Principle is the concept that claims that as the velocity of a fluid increases, its pressure decreases. Daniel Bernoulli was an 18th century scientist who discovered this principle. More » Science Physics Motion & Mechanics

One way to calculate the pressure drop of fluid through a pipe is using the Reynolds number, which is equal to the velocity of the liquid's flow multiplied by the diameter of the pipe and then divided by the kinematic vi... More » Science Physics
