Static pressure refers to the pressure of a fluid or gas that is not in motion. It is typically measured in pounds per square inch (psi) or kilopascals (kPa).
In the context of firefighting, static pressure is often used to refer to the pressure of a water supply, such as that provided by a fire hydrant. This pressure is important because it affects the ability of firefighting equipment, such as hoses and pumps, to effectively deliver water to the fire.
High static pressure can make it difficult to control the water flow, while low static pressure can limit the amount of water that can be delivered to the fire. Firefighters must take static pressure into account when selecting and using firefighting equipment, and they must also monitor the pressure throughout the course of the fire to ensure that it remains within acceptable limits.
