Q:

What are some examples of the Bernoulli equation?

A:

Quick Answer

One example of the Bernoulli equation in action is airplane wings. The design of an airplane's wings cause the pressure below the wing to be greater than the pressure above the wing. This creates an upward lift towards the area of lower pressure.

Two semitrucks passing each other on the highway is another example of the Bernulli equation. The narrow space between the two trucks creates an area of low pressure. The pressure between them is lower than the pressure on the outside of the trucks. The trucks are pushed together towards the area of low pressure. The Bernoulli principle states that streamlines of fluid particles are far apart when the area surrounding them is wide. When the area is narrow, the streamlines are pushed together. The pressure in the fluid decreases and speed of the fluid increases. In these two examples, air is considered a traveling fluid.
