Hydraulics basics

Pascal's law

In fluid mechanics, the statement that in a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container. The principle was first stated by Blaise Pascal, who also discovered that the pressure at a point in a fluid at rest is the same in all directions, and that the pressure would be the same on all planes passing through a specific point.
