What is the flow rate range for a 2-inch hose?

The flow rate range for a 2-inch hose is generally understood to be between 150 to 200 gallons per minute (gpm). This range is typical for standard high-capacity delivery situations, allowing firefighters to deliver a significant amount of water quickly and effectively, which is essential in dealing with various fire conditions.

The larger diameter of a 2-inch hose allows for greater water flow compared to smaller hoses, facilitating a more robust response during firefighting efforts. The amount of water flow can be influenced by factors such as nozzle design, pressure at the source, and friction loss in the hose, but the general consensus within fire service standards supports the 150-200 gpm range for this size of hose.

Understanding the flow rates associated with different hose sizes is crucial for effective fireground operations, as it impacts water delivery strategy and coordinated firefighting efforts, ensuring that sufficient fire suppression capabilities are maintained.
