Which hand line is designed to carry up to 350 GPM?

The correct choice is based on the typical characteristics of the hand lines and their designated flow capacities. A 3-inch hand line is designed to handle larger volumes of water and is capable of delivering flow rates of up to 350 gallons per minute (GPM) or more. This size is used for significant fire suppression efforts, particularly in large fire incidents or situations where a substantial volume of water is necessary to effectively combat the fire.

The other hand line sizes, such as 1.5-inch, 2-inch, and 2.5-inch lines, generally have lower flow rate capacities. The 1.5-inch hand lines typically deliver around 100 to 200 GPM, suitable for smaller fires or for use in residential settings. The 2-inch lines can usually carry around 200 to 300 GPM, making them suitable for moderate fire scenarios. The 2.5-inch lines can deliver approximately 300 GPM but are still below the maximum capacity of a 3-inch line, which is specifically designed for high-volume water flow situations required in more significant firefighting operations.
