...following rule will be generally applicable, viz.: the pressure of water against a plane surface is equal to the weight of a column of water, whose base is the surface and whose height is its head of water. EG, if the other circumstances are the same, a wall... | |

...then filled the cask and the tube with water. The effect of this was to burst the cask ; for there was a pressure on the bottom of the cask equal to the weight of a column of water whose base was the bottom itself, and whose height was equal to that of the water in the tube (80). 82. Hydraulic... | |
