Proposal for highly pressurized water to raise a space tower and to produce kilometers-long water streams to fight wildfires.

Follow up to this post:

Pumping pressurized fluids to high altitude for the space tower and for
fighting forest fires.

In that post, I had thought we would need a secondary pump, such as a ram
pump, to convert from high volume, low head to low volume, high head,
because I didn't think there existed pumps high in both.

But in fact there are existing high volume, high pressure pumps that can be
used singly to send water streams kilometer distances to fight forest fires
and deliver water to drought stricken areas:

fighting forest fires, Page 2: high volume, high head, single pump solution.

Moreover, it might be possible to send the flow kilometers distance without
a pipe through the phenomenon of laminar flow. Laminar flow is an
interesting phenomenon in its own right. Some examples of it are shown in
the videos in the blog post.

water from 4,000 feet up will evaporate, and turn into a light water
vapor mist at ground level.

also what is the flow resistance of a 4,000 foot vertical pipe ?

note your flow rate at 380 gpm is no good for firefighting at all.

380/60 = 6 gallons per second.

Even a rain if it lasted for hours could extinguish a forest fire.

The expected loss in pressure for long distances is given by the calculator
at the link for the Hazen-Williams equation.

The 380 gallons per minute is actually in the high range for the largest
handheld hoses used by fire fighters in the 5" diameter range. But in any
case you would use multiple water streams like any large fire.

Take a look at the laminar flow videos in the post. The cohesiveness of
the flow is quite surprising. The length of the laminar flow streams will be
longer than the usual streams. The question is how much longer? I don't
think anyone knows the answer to that.

Bob, at first glance, this one reads like you've lost your damn mind.
