Pressure in liquids

A liquid presses on everything in it and on every wall of its container. The deeper you go, the more liquid there is above you, so the pressure grows with depth: water squirts farthest from a hole near the bottom of a bottle, divers feel it in their ears, and a dam is built much thicker at its base than at its top. At one depth the pressure is the same in every direction, and it doesn't depend on the container's shape, so in connected vessels the liquid settles at the same level in every one, however different they look. Water towers and pumps use this to push water up into homes.

Depth 1 · Foundation

You know that the pressure in a liquid grows with depth and is the same at the same depth in every direction, whatever the container's shape, and you can use that to explain jets from holes, thick dam walls, connected vessels and water towers.
