Another term for head pressure is __________ pressure.

Head pressure is commonly referred to as elevation pressure. This term is derived from the concept that head pressure is associated with the height of the water column above a given point, which directly affects the pressure exerted at that point. In firefighting, understanding head pressure is crucial, as it helps in calculating how high water can be delivered and the necessary adjustments that need to be made for effective firefighting operations.

Elevation pressure specifically refers to the potential energy available due to the vertical distance water must be moved. This understanding is essential when determining the required pressure to overcome gravitational forces and deliver water to the necessary height for firefighting efforts. As such, this term accurately reflects the relationship between the vertical elevation of the water source and the pressure it exerts at various heights.
