Head in a water distribution system is measured in what unit?

Head in a water distribution system is indeed measured in feet. This measurement represents the height of the water column that would produce a certain amount of pressure at a given point in the system. In the context of water distribution, head can refer to various types of head, such as static head, dynamic head, or pressure head, which all contribute to the overall energy in the system.

Feet is typically used in the United States for measuring head in water systems because it aligns with the common engineering practices and standards in the country, making it easier for professionals in the field to communicate and compare data.

While inches, meters, and millimeters can also be utilized in certain contexts, they are less conventional for expressing head in water distribution within the US. Feet is the standard unit that allows consistent engineering calculations and assessments in water systems, reinforcing its importance in practical applications and system design.
