What would be the psi equivalent of a 5-foot water column?

To determine the psi equivalent of a 5-foot water column, you can use the relationship that 1 foot of water column equals approximately 0.433 psi. This means that to convert feet of water into psi, you multiply the height in feet by 0.433.

For a 5-foot water column, the calculation would be:

5 feet * 0.433 psi/foot = 2.165 psi.

This value is rounded to 2.16 psi, which corresponds with the answer provided. By using this standard conversion for water columns, it confirms that the conversion factors directly relate the height of water to the pressure exerted.

Understanding this concept is crucial for those working with wastewater systems, as it helps in evaluating the pressure at various points in the system based on the height of water that a system must support.
