The simplest siphon tubes are operated by simply filling the tube with water (by immersion in the canal, or other means), keeping one end in the canal and with the other end sealed, placing it in the area to be irrigated. The seal can then be removed and the water will siphon transferring the water from the submerged higher end to the lower end.
For example, if the tube from the upper reservoir to the top of the siphon has a much larger diameter than the taller section of tube from the lower reservoir to the top of the siphon, the shorter upper section of the siphon may have a much larger weight of liquid in it, and yet the lighter volume of liquid in the down tube can pull liquid up ...
Siphons in molluscs are tube-like structures in which water (or, more rarely, air) flows. The water flow is used for one or more purposes such as locomotion, feeding, respiration, and reproduction. The siphon is part of the mantle of the mollusc, and the water flow is directed to (or from) the mantle cavity. A single siphon occurs in some ...
Heron's fountain is not a perpetual motion machine. [2] If the nozzle of the spout is narrow, it may play for several minutes, but it eventually comes to a stop. The water coming out of the tube may go higher than the level in any container, but the net flow of water is downward.
The water level at each end of the tube will be at the same elevation, whether the two ends are adjacent or far apart, so a line between them will be horizontal at its midpoint and a shed base, building foundation or similar structure laid out using several such lines will be "horizontal" within building tolerances on any scale over which use ...
The design was first reported by McCarthy (1934). [2] As shown in the diagram, a stoppered reservoir is supplied with an air inlet and a siphon.The pressure at the bottom of the air inlet is always the same as the pressure outside the reservoir, i.e. the atmospheric pressure.

At 5500 meters above sea level the air pressure is 500 millibar while the air pressure at sea level is 1000 millibars. If you place a 1 liter bucket of water at 5500 meters, have the tube raise up to 1 meter above that and then extend down 5500 meters to 6 feet above ground, it will still siphon even though the air pressure is working against it.
