What is the expected flow rate for a standard high-rise pack used in firefighting?

The expected flow rate for a standard high-rise pack used in firefighting is set at 266 gallons per minute (gpm) due to the operational demands of high-rise firefighting. This flow rate is particularly important as it is designed to provide adequate water supply to combat fires effectively in tall buildings, where higher pressures and longer hose lengths can complicate the water delivery system.

In high-rise firefighting scenarios, the substantial flow rate ensures that firefighters can deliver sufficient volume to suppress fires quickly, while also accommodating for potential losses due to friction in the hose or other factors. Furthermore, the 266 gpm flow rate aligns with the capabilities of fire pumps typically used in urban settings, allowing for a balance between effective suppression and the limitations of high-pressure systems.

Understanding this standard flow rate is essential for fire engineers and crews when strategizing water supply and hose deployment in high-rise incidents, as it aids in matching the needs of the firefighting operation with the resources available.
