If you take a mile of hose, or one 50 foot length, what percentage of the single

and hose diameter? 100%? You don't really think so, do you?

I know from my experience that two hoses in series deliver significantly less
water than one. Now multiply that effect for a 500 foot hose.

For tapping beer from kegs, they even use the line length to drop the pressure
to avoid foaming. 3/16" beer line produces 2 psi drop per foot at the flow of a
normal tap.

You had better put down that sudz.. you don't know the difference
between pressure and volume.
