Where do you go to find a standard 220v electric waterpump with best
pressure to weight ratio?
Could it be strong enough to selflevitate if pushed against ground,
mm, cm or even a meter?

Depends on how massive the extension cord is - the extension cord for
the water. Put a hundred kilovolts on it and it will levitate without
spewing water,

Well i did not to build an electric boiler myself, and certainly not a
turbine.
I just need a strong pump, with good psi to weight ratio.

Acually AI it is for a fountain so no extension cord for water needed,
just an adjustable nozzle and a waterproof enclosing.
What is the physic theory for a fountain on a scale if you adjust the
pump nozzle pressure levitating water in the air, will there be a
force pushing scale down? A weight gain, weight loss or will the scale
remain indifferent.

So what happen if you put a thin bowl shaped fountain it is
waterfilled and with a pump it stand on a scale and go from zero psi
to max?
Will the scale show weight decrease due to water pumping in air, or
weight increase due to recoil force from the pump pressing it down or
does the system remain indifferent on the scale?
Nobody knows the answer to the question? Someone must have tested this
i would say there is a force pushing fountain down but due to the mass
redistribution when water move upward it will lose weight.
But what is the neteffect of the fountain + or - weight on scale?

When you answered the question you can try this one what will happen
if the bowl fountain is enclosed with an upper bowl and some engineous
device evaporator manage to vaporize the steam before it reach the
upper bowl.
Now maybe the bowl isn't actually bowl shaped more like plate shaped
or disc shaped where goes the forces?

Consider the case of pumping one small drop of water
at arbitrary velocity. The change in weight of the water
is very small, but the recoil force is arbitrarily large. So the
scale reading can go up.
Now keep doing this. Eventually, all the water will be gone.
No more recoil force. The scale reading can go down
(better put a slight angle on the nozzle, or the rain of droplets
may complicate things).
The general case
When you start pumping, it doesn't matter
how much water you pump. You can't pump it with
less recoil force than it weighs. So at the beginning
the reading must go up (by an arbitrarily small amount).
At the end the reading will be decreased by the weight of
the water.
While you are pumping the reading can go down
(by whatever water has been pumped) or can be
arbitrarily high.

Air compressor and the tank full of water will make a las vegus squirt .
200 psi tank and a ball valve on a 2 inch line to a 50 gal ac tank full
of water with a pipe out the bottom bent and pointed up to shoot up.
A steam coil will be better then the air compressor.

I am not sure about the recoil to weight ratio, what i do not
understand is that there seem to lack a formula for the case it seem
pretty basic math,
And i think you forgot we talk about fountains here so we probably
should incorporate gravity letting the water go down also, it will go
down to the bowl at same rate as up if the pressure is constant.
But as long the pressure increase there will be a climbing water
weight decrease and a raising force pressing the bowl down. But again
where is the formula for a fountain on a scale?
[quote]Now keep doing this. Eventually, all the water will be gone.
[/quote]
I've never seen fountain running out on water except for small amount
vaporised by heat of sun. But my fountain run in an enclosed system so
i can not see how.
Where do you think the water did go, ;D
[quote]No more recoil force. The scale reading can go down
(better put a slight angle on the nozzle, or the rain of droplets
may complicate things).
[/quote]
Well if we assume a straight nozzle only levitating a pillar of water
straight up there will not be that much droplets until the water hit
the surface of pound in fountain.

[/quote]
So when the fountain find a constant flowrate levitating a 30 cm
pillar of water that also fall back into fountain pound due to
gravity, will it have a + , - or = original weight?
Your general answer seem to be that the water pushing force and the
recoil force extinguish eachother and leaves you with the weight loss
of water pumping up, *but it must come down to with a force at surface
of pound* or does gravity have a recoil?
There is something missing here surely there must been some people
tried to find out a general formula for fountains.
[quote]While you are pumping the reading can go down
(by whatever water has been pumped) or can be
arbitrarily high.
[/quote]
I find your answer both fuzzy and not so convincing, in fact i am
quite sure you did not answer the question.
Questions.
1. +,- or unchanged *during the raising of pressure*
2 +.- or unchanged *during the constant rate of flow*

No better put some AI's on doing the math i feel exhausted.
But it seem like the thrust *vaporize* and create pressure in every
direction and there is a recoil in the system.
So you have a waterpiston with recoil forces and a thrust force that
is evaporated to only cause a pressure change, it is a closed system.
The system would probably be quite similar to a cooling device with
evaporator in one end and cooling in the other. The evaporator will
probably cause quite a pressure inside the flying refrigerator so
there will be no problem to drive the pump.
So where do you buy plateshaped refrigerators.
