Could something that transfers water through capillary action[a rope, cloth, or whatever else is better at this] theoretically be attached to a balloon a mile high and still raise water from whatever body of water the lower end is submerged in?
There are no free energy machines, soβ¦
When water climb up a dry towel against gravity making the whole towel wet. The energy has to come from somewhere?
So if I understand it directly, pumps located upstream can pump water to a height of 30-34 before vacuum forces become dominant. How much could we increase this height if smaller diameter tubing was used where capillary action is significant? Anyone have resources for such calculations?
suppose I dip a paper towel's edge in a bowl of water, and observe the water flowing up. The center of mass of the combined water/paper-towel system is slowly rising as long as capillary action is progressing (right?) which means that we are moving towards a higher gravitational potential energy state. What energy sources are being "spent" as this is happening, such that we end up with net zero change in energy?
Hello.
This is a question from a person without any background on physics.
If I was aiming to reduce the velocity/time in which a substance diffuses through a tube of known dimensions and length (e.g. 5um x 5um x 5um) which is parallel to the floor in which I do not apply any pressure whatsoever with vacuum generator etc., and the temperature is constant, would exchanging the solvent of the substance with a solvent of much higher viscosity work?
I was looking at the Washburn's law but I do not know if my Polydimethylsiloxane structure can be considered as a porous medium.
Thanks!

(Hope thatβs ok to post. My other edits got removed and this is a useful one.)
Assuming a substance (example: water in a tree) has risen in height, it now has the potential energy that it didnβt have at the bottom of its path.
