What is the Maximum flow out of a 5 inch fire hose?

The maximum flow rate out of a 5-inch fire hose can vary based on factors such as the pressure applied and the hose's design. However, under optimal conditions, a 5-inch fire hose can deliver approximately 1,000 to 2,000 gallons per minute (GPM) when supplied with sufficient pressure. The actual flow rate will depend on the specific circumstances, including the length of the hose and any obstructions.
