What is the flow range for 2 inch attack hose?

• A. 80 - 200 gpm
• B. 100 - 250 gpm
• C. 120 - 300 gpm
• D. 140 - 350 gpm

Answer: (B)

The flow you can get from a 2 inch attack hose is determined by the hose size, the nozzle type, and the pressure you can safely apply at the nozzle. In typical fire attack situations, a 2 inch line is capable of delivering about 100 to 250 gallons per minute. The lower end covers smaller tips or some friction losses, while the upper end comes from larger tips or higher usable pressures on that same hose. Flows well below 100 gpm usually mean a very small nozzle or significant hose friction, and flows above roughly 250 gpm would require conditions or equipment beyond what a standard 2 inch handline is designed for. So, 100–250 gpm is the range that fits normal use for a 2 inch attack hose.
