What pressure will one psi exert in terms of feet?

One psi (pounds per square inch) can be converted into feet of water column using the relationship between pressure, density, and gravitational force. Specifically, 1 psi is equivalent to 2.304 feet of water at standard conditions. This conversion is based on the fact that water weighs approximately 62.4 pounds per cubic foot, and knowing that there are 144 square inches in a square foot helps facilitate this calculation.

Since pressure is defined as force per unit area, 1 psi translates to a height of water that can exert that same pressure due to gravitational effects. The unique relationship and that established conversion factor makes 2.304 feet the correct answer. This figure is crucial for fire service pump operators as they often need to calculate pressures and heights of water columns for effective operation and management of water supply systems.
