What is the friction loss coefficient for 5" Snap-Tite hose?

The friction loss coefficient for 5" Snap-Tite hose is established at 0.05 PSI per 100 feet of hose. This low friction loss value is significant in fire rescue operations, as it indicates that this size of hose is designed to allow a greater flow of water with minimal resistance. This characteristic is crucial for maximizing water delivery when responding to emergencies, as it enables firefighters to maintain strong water pressure over long distances without significant losses.

Understanding the friction loss coefficient is vital for effective fireground operations. When calculating total pressure loss in a hose line, knowing the specific coefficient helps firefighters and engineers determine the necessary pump discharge pressures to ensure adequate flow rates at the nozzle, which directly impacts firefighting effectiveness.

In contrast, other coefficients like 0.15, 0.20, or 0.10 PSI represent higher resistance and would indicate a less efficient flow for firefighting purposes, thereby making the selection of the correct option essential for operational efficiency.
