Which hose size has a flow range of 40-125 gpm?

• A. 1.5 inch
• B. 1.75 inch
• C. 2 inch
• D. 2.5 inch

Answer: (A)

Flow depends on hose diameter and the nozzle setting. A 1.5-inch handline is designed for moderate to lighter fire streams and is typically paired with nozzles that can deliver from roughly 40 gpm up to about 125 gpm, depending on the nozzle and pressure. Larger hoses, like 2 inches or 2.5 inches, are used for higher flows and more volume, so their common nozzle configurations deliver well above 125 gpm. Because the 1.5-inch line can produce flows across that 40–125 gpm range, it best fits the given interval.
