The concept of the Fire Stream Triangle Is that your agency needs all three sides to develop Gold Standard Fire Streams from Master Streams to Handline Streams.
A hose with low kink, low nozzle whip, appropriate weight, proper friction loss vs. water velocity for flow. A robust construction to combat thermal and mechanical insult on the fire ground and attain a service life of 10 years with no elongation or delamination issues. The diameter on the hose will actually be the internal diameter of the hose. While this alone will not be, and there is no, silver bullet, this is a step in the right direction. This is “True Hose”
Still trying to "expand" my knowledge.. My thoughts today on both Air Entrainment and Steam your mileage may vary.
I do not know who said it first, but "I like to have a long distance relationship with fire". They understood the best way to achieve this was with a high application rate and low nozzle reaction (straight or solid stream).
Lets take a moment to talk about how to protect yourself from thermal failure of hose issues regardless of spec. Hose line burn through is potentially a significant factor in some LODDs. Neglect of basic hose line handling and maintenance along with improper hose spec are the major contributing factors to burn through.
Consider the following:
