What is another term for head pressure?

Head pressure refers to the pressure exerted by a column of water, typically measured in feet or meters, based on its elevation above a specific point. Elevation pressure is indeed a term that describes this phenomenon, specifically the pressure resulting from the height of the water above the point in question. In fire protection and emergency services contexts, understanding head pressure is essential because it affects water delivery systems, hydrant operations, and other aspects of fluid dynamics when responding to emergencies.

Static pressure refers to the pressure in the system when there is no water flowing. Flow pressure is the pressure measured when water is moving, while residual pressure is the pressure remaining in the system when water is flowing. These terms, while related to pressures in a fluid system, do not specifically refer to the pressure created by elevation, making elevation pressure the most appropriate synonym for head pressure.
