How do you calculate head pressure?

To calculate head pressure, you need to understand the relationship between head height and pressure in fluid systems. Head pressure is typically measured in feet of liquid column, and the conversion to pressure (in pounds per square inch, PSI) involves dividing the head height by a specific factor, which in this case is 2.3. This factor (2.3) is derived from the density of water and the conversion formulas used in hydraulics.

When you divide the head height by 2.3, you are converting the height of the water column into a corresponding pressure measurement. This conversion is crucial in various applications, including water distribution systems and understanding how changes in water height affect the pressure experienced in a system.

The other options do not reflect the correct mathematical relationship needed for this conversion and would lead to incorrect calculations of head pressure.
