What are the two GPM ratings for the vari-nozzles?

The correct answer, which refers to the two GPM (gallons per minute) ratings for vari-nozzles, is significant because vari-nozzles are designed for versatility in firefighting applications. The ratings indicate the different flow rates that can be achieved with the nozzle, allowing firefighters to adjust the water output according to the specific needs of the situation, such as extinguishing fires or protecting structures.

In firefighting operations, the appropriate GPM is crucial because it directly affects the ability to suppress fires, particularly in various environments and conditions. The 95 GPM and 125 GPM ratings provide flexibility for addressing both smaller fires and larger, more intense blazes while maintaining effective pressure and reach. This adaptability is essential for ensuring safety and efficiency in emergency responses, which is why these specific ratings are important for understanding the capacity and function of vari-nozzles in practical scenarios.
