Water lifted by gravity without a pump Part 2

[DPMANLA]

you keep your dog in that cage in the background ??? if you do shame on you. time out in a cage not rite how would you like it

[AndrewKFletcher]

@DPMANLA The crate is used for a puppy to save her chewing through live wires when we go to bed :)

Of course the density of the fluid makes a difference. Thermodynamic siphoning works because one side is hotter and thus less dense than the other colder and denser side. I don't understand what you are trying to show?

[AndrewKFletcher]

@homskoult Agreed, it was after I installed a new boiler with a flow and return system as you point out that I made a very important discovery that relies on molecular drag, rather than the siphon effect you refer to. A siphon effect for example cannot take place in the tube above the 10 meter atmospheric limit, and a siphon cannot take place when both open ends of the tube are at equal level to the ground. More to the point, if we join both ends of the tube this density flow will occur.

wt do u mmean by the negative tension

[AndrewKFletcher]

@stooncol619 Cohesive tension applied to the molecules causing molecular drag which affects all of the water molecules inside the tube. Movement down one side causes movement up the other side. Pressure inside the tube is reduced by the downward momentum of applied gravity to the water. I should have said negative pressure and tension applied :)

[stooncol619]

@AndrewKFletcher thanks>>>>>>>>>> wt can i do to know more about that >any websites recumended  thanks

[Mauromoustakos]

Nice initiative, most useful for public education.

We should have been able to see the two tubes separately with more easy. The two vessels are too small (even two drinking glasses will have done better). The hanging point is inconveniently high. Background not thought off, just any room doesn't do. Sound and/or pronunciation not perfect (but I am no native speaker).

@Mauromoustakos Thanks for the comment and the points you made about the video. Have uploaded another clearer video a while back showing the same experiment using soft walled silicon tubing to show how the pressure changes inside. The video is under the heading stenosis. Andrew

Come on, Total waste of water. LOL

[InclinedTherapy]

@overunitybill2009 Flushing the toilet is a total waste of water, showing how gravity acts differently on fluids in one length of open ended tube is anything but a waste of water. Physiology Literature states that gravity has no affect on circulation because it acts equally on the arterial and venous blood. This video shows how minute changes in density are affected by gravity and how this uneven influence can and does have an affect on fluids in tubes, including the tubes in your body.

[mojokiss]

what i get out of this is a possible better understanding of how salt in my body works as a pump. Makes me appreciate how salt may be used to regulate waterborn functions in my body.

[AndrewKFletcher]

@mojokiss Glad you applied this simple yet hitherto overlooked density flow to your bodies salts. Inclined bed therapy is worth a google to understand what happens when a bed is elevated at the head end by 15 cm's to afford a level but tilted mattress. My wife and I conducted analysis of urine produced sleeping head down, horizontal and head up. Head up produced much denser urine. Head down produced urine without salts, very close to water density. This should help doctors to understand IBT

I had a dream this dude was doin surgery on me while i was awake... i wouldn't piss him off. using gravity is the only possible prpetual motion on earth, its the only non stop energy everywhere on earth, and the spin of the earth...

[herreryx]

@terribletoys Until the salt solution runs out. Therefore not perpetual :P

[AndrewKFletcher]

@herreryx @herreryx The salt is always present inside the tree! Evaporation will alter it's density. Gravity must act upon density changes! so circulation is governed by evaporation rates and available ground water. Trees die as do all species, so in a tree at least this system has limitations.

The experiment is designed to show what happens after evaporation.

[AndrewKFletcher]

@terribletoys Mentioning perpetual motion gets everyone's backs up. Fortunately for us, life is indeed perpetual in that it constantly replicates where sustenance is available. The weather is indeed perpetual as are the waves in the sea, together with the constantly recycling of the Earth's crust. The formation and decay of planets is perpetual and as you rightly say the constant pull and push from gravity is what counts. Astronauts experience accelerated ageing in space.

Cool experiment and explanation

[kokopelli314]

Nice demonstration of fresh vs. salt water density. If you use solar evaporation then condensation in a nice tight closed loop you could extract some energy.

[Shrike2415]

If the overflow of one bottle fed into the other bottle that was draining, could this somehow create a perpetual flow system?

[AndrewKFletcher]

@Shrike2415 The water level in the upward flowing side goes much lower than the overflowing side, ruling out siphon. Both tubes are at equal levels on the bottom of the bottles. If we use one bottle as you suggest, the experiment will obviously only fow as long the salt is flowing down.

In a tree, the sap circulates, evaporation from the leaves alters the density and the sap is rediluted by water from the soil at the roots. Not strictly perpetual although trees have grown perpetually on earth.

[goldgait1]

Monks used this tech to move water up hill centuries ago

[AndrewKFletcher]

@goldgait1 Do you have a reference to this so I can check it out? Thanks Andrew

[goldgait1]

Yes, take a plain plastic tee insert the tubes in the two water containers as you have now, on the third tube that comes off the tee blow into the tee which creates a vacume thus moving water fom one container to the other. you can do the samething by adding water instead of blowing air into the tee and it will move water two to one.

[AndrewKFletcher]

@goldgait1 You refer to the same mechanism as in a compressed air spray gun? This takes energy I.E. air pressure to lift the water and is also subject to the the 32 feet limit that Galeleo and Torriceli faced while trying to draw water up a pipe in a 40 feet deep well. Yes this mechansim does have some effect in the leaves of trees and assists transpiration. BUT cannot explain water transport in trees for various well established reasons.

[goldgait1]

No compressed air, what I am reffering to is vacume created when you pour 2 units of water into a tee perducing 1 unit of movement no air compressure no man made anything. Research ! Again old tech

[InclinedTherapy]

Hi

The side that the salt flows down causes the vessel to overflow, once the flow starts the rest of the coloured salt solution is dragged along in the same direction as is the salt free water causung the vessel to overflow.

The experiment went a little wrong in that the syringe was sucked up fully by the tension applied to the water column when it was elevated. I should have held it back and allowed a tiny amount of salt to be released at a time so you could see a coloured pulsatile flow

[Justalabrat]

what determines which tube is input (empties cup) and which is output (fills cup)
