Bernoulli's principle

---

A common example of Bernoulli's principle is the water tank with a hole is the side. This demonstration simulates that example. A cylindrical column with two holes in its side is filled with colored water. As the water flows out of the holes it falls in a parabolic trajectory as shown in the figure below.

Bernoulli's principle allows us to show that the velocity of the water coming out a hole is related to the height of the water level above that hole in the column. The water coming out of the top hole does not go as far as the water from the bottom hole because it has less water above it. You can trace the change in the path of the water as the water level falls in the movie.

1. Why does the water fall in a parabolic arc?
2. Name three other examples of Bernoulli's principle.
