If the pressure is measured as 30 psi, how tall would the corresponding water column be in feet?

To determine the height of a water column that corresponds to a pressure of 30 psi, you can use the relationship between pressure and the height of a water column.

The formula to convert pressure in psi to the height of a water column in feet is:

[ \text{Height (feet)} = \text{Pressure (psi)} \times 2.31 ]

This conversion factor (2.31) is derived from the fact that 1 psi can support approximately 2.31 feet of water at standard conditions.

Applying this formula for 30 psi:

[ \text{Height} = 30 , \text{psi} \times 2.31 , \text{feet/psi} = 69.3 , \text{feet} ]

Therefore, when the pressure is 30 psi, the corresponding height of the water column is 69.3 feet. This calculation method is crucial in wastewater management and other fields where fluid dynamics are important in understanding the behavior of fluids under pressure.
