What is one standard atmosphere at 14.7 lbs per square inch equivalent to in feet of water?

One standard atmosphere is defined as the pressure exerted by 14.7 pounds per square inch (psi) at sea level. To convert this pressure into feet of water, we can use the relationship between pressure, density, and height of a liquid column.

The pressure exerted by a column of water can be calculated using the formula:

Pressure (psi) = Density of water (lbs/ft³) x Height of water (ft)

For freshwater, the density is approximately 62.4 lbs/ft³. To find the height of the water column that corresponds to the pressure of 14.7 psi, we rearrange the formula:

Height of water (ft) = Pressure (psi) / Density of water (lbs/ft³)

Now, substituting the values:

Height of water = 14.7 psi / 62.4 lbs/ft³

Height of water ≈ 0.235 ft/psi

To find the height corresponding to one atmosphere, we multiply by the pressure of one atmosphere:

Height of water ≈ 0.235 ft/psi × 14.7 psi ≈ 34.5 ft

Since the closest standard measurement of this is typically rounded to a simpler figure,
