What is the coefficient value for a 5" hose?

The coefficient value for a 5" hose is 0.05. This value represents the friction loss per 100 feet of the hose, indicating how much pressure is lost due to friction as water flows through the hose. Understanding this coefficient is crucial for firefighters and driver engineers, as it allows them to accurately calculate the necessary pump pressure when operating with different hose diameters.

Using a specific coefficient for the 5" hose helps ensure that the system delivers sufficient pressure to effectively fight fires while also accounting for the distance and hose length involved in the operation. In scenarios where precise calculations are essential, such as determining the needed flow rates and pump settings, relying on these established coefficients allows responders to operate safely and efficiently. Proper application of these values can significantly affect firefighting success and resource management during an incident.
