Improvements
[edit]Sources needed, for example: why's the poisonous water poisonous, why's it not potable?
The old, gravity powered aqueducts, potential energy due to altitude is slowly converted to kinetic energy, allowing it to be carried long distances. It's not simply controlling kinetic energy.
Today, water may be contaminated. What about in the past? In the future?
Should also refer to ground water since it must be pumped and there's far more groundwater than water in lakes and rivers.
How do we pump above 11 meters from groundwater? If one forms a vacuum above water, it'll move up at most about 11 meters due to the pressure of the atmosphere, but what do we do when we need it to go higher?

Discharge height
[edit]The claim that the pumps described here can deliver water to 5-10m above the outlet is incorrect. The maximum height they can deliver to is the height of the highest point of the pump, as a basic understanding of hydrostatics will tell you. http://en.wiki.x.io/wiki/Communicating_vessels 2003:C4:FF2D:8D44:99FA:6EF9:46AE:40D0 (talk) 07:48, 20 May 2024 (UTC)
