Self Siphoning Water

[therealrasta]

Well water cannot be compressed and air can... I guess I was thinking optimistically when I thought the specific gravity of the water would be able to over power the air pressure.

@Free Energy,
Here is what I came up with. I decide ed to try doing it on my paint program.
What I like about having a reservoir on top is the "cool" factor. Everybody is used to seeing water drain at the bottom of a pipe, but at the top ?
I think that is something that would catch people's attention. Of course, the larger the volume of the top reservoir, the more vacuum that would be needed. it's shape could be modified to lessen it's volume.
Of course, like anything else, to see if it works would take some careful work to have everything set up properly. Then by knowing all the different values, it could be properly tested.
edited to add; and of course, the water level in the top resrvoir would always stay at the same level !!!

p.s. in my previous post with the 2 cylinders, the 5 pounds of water only creates 1 psi of downward pressure if the surface area of the tube is 5^2". I said it is still only 5 psi the second time I mentioned it. I should have said 1 psi.

in your drawing i don't think the water reservoir will hold the same level of water during its process, the water would run out and air bubbles would go up the tube and it would lose vacuum in the reservoir section. the system would stop. this is why i would use equal diameter tubes. i dont even think a vacuum is necessary, it might help or not gotta try it out.

-edit-
need to try my original idea in this thread!

hi guys,

i've been watching this thread but still can't figure out what you are trying to accomplish.  are you trying to get a continuous flow of water to drive a power source?

tom

um, no that's not it at all, complete opposite of that!
are you here tell us these kind of ideas will NEVER work? lol

  Tom,
Initially, just to see if a continuous flow can be achieved. If so, then that alone would be something.
And since it would have a drain, it would be possible to power a water wheel. Wouldn't generate much energy, but could generate interest in alternative engineering.

  @All,
Had a thought about filling the system. What is interesting is by back filling it, by putting a tube oover the discharge and creating a greater static head, water could flow thrrough the drain into the resrvoir on top and then into the inlet pipe.
And then, when the fill tube is removed, it would either work or not work. I think the reservoir being filled to the level of the inlet pipe would help it to flow quicker if it were to work. A small detail that I think is important to remember is that the reservoir could only be filled to just below the level of the inlet pipe to maintain seperation between inlet and discharge sides of the system.

@Free Energy, when the drain tube curves up, it creates a trap that won't let air in. Under your sink, it is called a loop seal that keeps sewer gasses from flowing out of your sink.
                                                                   
edited to add; This might also help some to understand how I think Bessler's wheel worked. I do believe he used water.

which way is the water flowing?


--edit--

never mind, i see it now!
when the water reservoir fills up to a certain water level the water gets flushed!

Your idea made me think of using 2 concepts to create 1 result. It uses siphoning action and the fact that a high enough water column can overcome athmospheric pressure. However the big IF is whether indeed a siphon action will take place and cause a vacuum at the top of the sealed container instead of break down the water continuity and cause a vacuum at the top of the tubes.

Siphons in vacuum work but combining that with a water column high enough to overcome atmospheric pressure is new to me. If it indeed creates a vacuum at the top of the sealed container then you can guess yourself what benefits that has.

33-34 ft is the magic number.  at about there the "water continuity" you talk about is actually cavitation.  water can no longer stay together.  if less than that height, no worry.  the weight on both sides (to the water level of the tank) of the tube will be equal.  as long as the exit tube is lower than the top of the tank level, flow will happen provided the tank is vented (air can come in).  if you plug this vent, flow will stop and leave a partial vacuum in the tank.  depending on how far below the water level the exit tube ends will determine the amount of vacuum.  as mentioned above, the height above the water level (up and down) in the tube will cancel each other.

at this point if you attach another tank, provided the new tube is full of water too, that is below the exit tube of the first tank, water will flow back to that (lowest) tank.  this will cause the upper exit tube to empty.  if the 2nd tank is higher than the end of the 1st exit tube, and vented, the water will flow out the 1st exit tube.

let me know if anything is not clear.
