What is the best and easiest way?
Hmmm.a flat hose is going to be a problem every time.
A standard heavy duty hose will do for most gardening activities, and will not kink up on you.
I don't think you want the density of a vehicle, as that doesn't change, but the traffic density of vehicles on the highway. The density in vehicles per mile is just a calculation. You have 50 vehicles in a 0.5 mile stretch, you have 100 vehicles per mile. Density doesn't change with speed, except as peoples driving rules change. If it changes, you just count them at that speed, and recalculate. . .
A rolled up hose ain't gonna cut the mustard. You need to have a stretched out hose to put a beaver fire out!
I find that my marriage works better thanks to my hard wearing fireman's hose.
