Generally speaking, how many gallons per minute does a 1 ¾" fire hose line flow?

A 1 ¾" fire hose line typically flows between 120 to 180 gallons per minute (GPM). This range is important for firefighters to understand as it directly influences both the effectiveness of fire suppression efforts and the hose management strategies used on the scene.

The flow rate can be impacted by various factors, including the nozzle type, the friction loss within the hose, and the pressure being supplied. A hose of this size is generally used for structural firefighting or for situations where a higher flow rate is necessary to effectively combat the fire.

Knowing the range of flow helps firefighters in selecting the appropriate hose line for a given situation, ensuring that they can deliver adequate water to suppress the fire while considering the physical effort required to manage the hose effectively. The other ranges provided would not typically correspond to the flow rate of a 1 ¾" hose, making them less accurate for this specific diameter. Understanding the correct flow rate aids in efficient firefighting operations and overall safety on the fireground.
