Bernoulli's equation explains the relationship between pressure, velocity, and height in fluid dynamics.

Our mission is to provide a free, world-class education to anyone, anywhere.

In the article on fluids and Bernoulli's principle they explain that if the pressure is lower at one point (where the pipe is narrower), the velocity is higher as opposed to another point where the velocity is lower and the pressure is higher (where the pipe is wider).

Bernoulli's equation is a principle of fluid dynamics that describes the behavior of fluid flow.

I just watched the chapter " checking if an equation represents a function and am thoroughly confused. in the example, he is solving (x-3) = y Squared ( sorry, I do not have a way to type the small 2 for squared) he takes the square root of y and the square root of x-3 and says y squared can be positive or negative. but why?

Bernoulli's equation relates the pressure, velocity, and height of a fluid in steady flow.
