Generally speaking, a 1½" (38-mm) attack hose can flow __________.

A 1½" (38-mm) attack hose is commonly used in firefighting for its balance of maneuverability and water flow capacity. The correct flow range for this size of hose typically falls between 60 to 125 gallons per minute (GPM). This flow range is optimal for effectively attacking fires, allowing firefighters to deliver a sufficient volume of water to suppress flames while keeping the hose manageable for quick movements and deployment in various scenarios.

This capability supports efficient firefighting operations, which requires timely and adequate water delivery to control and extinguish fires, especially in residential or small commercial settings where agility and access are crucial. Larger flow rates beyond this range, while possible, would generally require larger diameter hoses or multiple attack lines to ensure safety and effectiveness. Understanding these flow dynamics helps firefighters select the appropriate equipment for specific situations, enhancing both operational efficacy and safety.
