Bernoulli's Bucket | @CMofDenver #physics #science

Exhibit from the Children's Museum of Denver Marisco Campus.

A bucket of water is connected by hose to a spout. When the bucket is lifted the water comes out of the bucket faster. Neglecting friction, regardless of how high the bucket is lifted, the water will rise up to the same height as the bucket.

This is an application of Bernoullis' Law, or Bernoulli's Principle.

In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. The principle is named after Daniel Bernoulli, a swiss mathemetician, who published it in 1738 in his book Hydrodynamics.

there has to be a limit right. If the bucket was a mile high then what?

Use a 5 gallon bucket and see what happens.

Is there a way to make this into one of those infinite energy generator things? Forgot what they're called, but it's somthing that generates more energy than it consumes, breaking some physics law
