What is the typical flow rate of a 5" hose flowing from a hydrant over a distance of 500 feet?

The flow rate of a 5-inch hose can vary based on several factors, including the pressure available from the hydrant, the nozzle used, and the length of the hose. However, a typical flow rate for a 5-inch hose flowing from a hydrant over a distance of 500 feet is around 700 gallons per minute (gpm). This figure is often used in training and operational settings to provide a baseline for calculations related to fire flow and water supply needs.

A 5-inch hose is designed for high flow and minimal friction loss, allowing it to effectively deliver large volumes of water. While actual flow can be higher, such as with certain configurations or additional pressure, 700 gpm is a reliable estimate for many firefighting situations, making it a common reference point in training scenarios. This understanding assists firefighters in calculating necessary water supply and planning operations when responding to fire incidents.
