A foot of head (water height) produces how many pounds per square inch of pressure?

A foot of head in a water column produces approximately 0.433 pounds per square inch (psi) of pressure. This relationship comes from the fundamental understanding of how fluid pressure works, particularly in water. As water is essentially incompressible, the pressure created by a column of water can be calculated using the formula:

Pressure (psi) = Height (feet) x 0.433

This means that for every foot of water height, the pressure exerted at the base of the column is about 0.433 psi. This conversion factor is crucial for water operators, as it helps them understand the pressures in water distribution systems and how changes in elevation affect pressure. Understanding this principle is critical for ensuring that water systems operate efficiently and effectively.

In this case, since the question asks specifically for the pressure produced by a foot of head, the correct answer reflects this specific conversion factor of water height to pressure.
