To determine how much pressure is exerted by a column of water, you can use the formula for hydrostatic pressure, which states that pressure (in psi) is equal to the height of the water column (in feet) multiplied by the weight per unit volume of water (which is approximately 62.4 pounds per cubic foot).

First, it’s important to convert the height of the water column from inches to feet because the pressure formula generally uses feet for the height. Since there are 12 inches in a foot, a column that is 12 inches high will be equivalent to 1 foot high.

When applying the formula for hydrostatic pressure:

  • Height = 1 foot

  • Weight of water = 62.4 pounds per cubic foot

The pressure exerted by the water column can be calculated as:

Pressure (psi) = Height (ft) x Weight of water (lb/ft³) / Area (ft²).

Since the cross-sectional area in this case is 1 inch x 1 inch, converting that to feet gives us:

Area = (1/12) feet x (1/12) feet = 1/144 square feet.

Now, the pressure at the base is:

Pressure =
