What is the term used to refer to the pressure created by a vertical column of water?

Explanation:
The pressure produced by a vertical column of water is called the head. This term comes from the idea that the pressure at the bottom of a fluid column is equivalent to the height of that column. Mathematically, p = ρ g h, so the head is h = p/(ρ g). In other words, a taller column exerts more pressure, and we measure that pressure in terms of how tall a column of water would create it. Elevation and depth describe position or distance, not the pressure due to the column of fluid, and general “pressure” isn’t as specific to the height of the water column.
