What is the typical GPM capacity of a 5-inch supply hose 1,000 feet away without being pumped?

The typical GPM capacity of a 5-inch supply hose, particularly when assessing its performance over a distance of 1,000 feet without being pumped, is influenced primarily by the hose diameter and the friction loss that occurs over that distance.

A 5-inch supply hose is designed to handle significant water flow, and based on common industry standards, it can allow for a flow capacity close to 1,000 GPM under optimal conditions. This capacity provides sufficient flow for firefighting operations, ensuring that enough water can be delivered to effectively combat fires and manage emergency situations.

In practice, while other factors like elevation change, the condition of the hose, and the specific situation can affect the exact flow rate, the figure of 1,000 GPM is widely recognized as a baseline for a 5-inch hose when considering the limitations of friction loss over the stated distance without the aid of pumping systems. This makes it a suitable and standard choice for approximate flow calculations in various operational scenarios.

Understanding this concept is crucial as it influences operational planning in firefighting and emergency response, ensuring adequate water supply can be achieved effectively.
