A friend of mine lives 16.8 miles from me. His well pump appears to have
died. I went there and checked it for him, and there is power going to
the submersible pump, but no water coming out. I also popped off the
well cover and can not hear any sound, where a pump can usually be
heard.

I told him that he need to get a well driller, or plumber who can pull
the pump.

Anyhow, I was just joking around, when I told him that he's welcome to
run a garden hose from my house to his place. We got to laughing about
this, and said it would probably take at least 500 50ft hoses.

It turns out I was way off.....
On my way home, I watched the odometer. He's 16.8 miles away.
That's 88,704 feet. (roughly 1775 50ft garden hoses).

Anyhow, this is just nonsense, but I was thinking about it, and wonder
if there would be any pressure at the end of 1775 hoses. First off, the
hoses would have to go thru culverts so they were not driven over. Then
the hose would be going up and down a lot of hills and valleys, in this
case, the hose would have to cross a large river, which in itself could
be a problem. But like I said, this is just nonsense, but I am wondering
if there would be any pressure? I sort of doubt it.

I've already connected SEVEN 50ft hoses (350ft) when I had frozen
hydrants, and needed to get water to my animals, and I could notice a
considerable slowing of the water, and its pressure.

Anyhow, just for grins, is there any way to calculate water pressure
thru a 5/8" garden hose per foot? And just to mention it, my pressure
tank gauge varies from 35 to 50lbs.


Sure,
Pressure at the other end of the hose is exactly the same as at the head
end.
Problem is friction. The issue is FLOW.

That isn't true. At some given pressure and some hose length, the
friction of the hose is great enough that the water effectively
forms a plug and the pressure will be X at the source end and 0 at
the far end.
