What is the flow rate range for large-diameter hose (LDH)?

The flow rate range for large-diameter hose (LDH) is recognized for its capacity to transport a significant volume of water, typically ranging from 350 to 1500 gallons per minute (gpm). This characteristic makes LDH optimal for operations requiring high water flow, such as supplying water to multiple attack lines or for large-scale firefighting operations.

LDH is designed to minimize friction loss, which allows for more efficient water delivery over long distances or to high-demand scenarios. This is particularly advantageous in combating large fires where substantial amounts of water are necessary to effectively suppress the flames. Understanding this flow rate range is essential for firefighters in planning and executing effective firefighting strategies.
