1 psi is equivalent to how many feet of water head?

The relationship between pressure and the height of water is crucial in various engineering and sanitation applications. One psi (pound per square inch) is equivalent to approximately 2.31 feet of water head. This conversion is derived from understanding the density of water and the gravitational force acting on it. Specifically, one psi translates to the pressure exerted by a column of water that is 2.31 feet high.

In context, knowing this conversion is vital for tasks such as calculating water supply systems, assessing drainage efficiency, or designing lift systems in sanitation facilities. It allows practitioners to convert pressure readings into a height measurement, which can be easier to interpret or visualize in the context of water systems.

Other options do not align with the established conversion factor, making them incorrect for this specific question.
