  2. Siphon - Wikipedia

    en.wikipedia.org/wiki/Siphon

    A siphon spillway in a dam is usually not technically a siphon, as it is generally used to drain elevated water levels. [34] However, a siphon spillway operates as an actual siphon if it raises the flow higher than the surface of the source reservoir, as sometimes is the case when used in irrigation.

    en.wikipedia.org/wiki/Heron's_fountain

    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.

  4. Siphon tubes - Wikipedia

    en.wikipedia.org/wiki/Siphon_tubes

    Siphon tubes are a basic implement used in irrigation to transfer water over a barrier (such as the bank of a raised irrigation canal), using the siphon principle. At the simplest they consist of a pipe with no working parts. To work they rely on the water level in the canal being at a higher level than the water level in the field being irrigated.

    If it were greater, air would not enter. If the entrance to the siphon is at the same depth, then it will always supply the water at atmospheric pressure and will deliver a flow under constant head height, regardless of the changing water level within the reservoir.

  6. Siphon (mollusc) - Wikipedia

    en.wikipedia.org/wiki/Siphon_(mollusc)

    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 ...

    en.wikipedia.org/wiki/Soda_siphon

    Soda siphons. As early as 1790, the concept of an "aerosol" was introduced in France, with self-pressurized carbonated beverages. [1] The modern siphon was created in 1829, when two Frenchmen patented a hollow corkscrew which could be inserted into a soda bottle and, by use of a valve, allowed a portion of the contents to be dispensed while maintaining the pressure on the inside of the bottle ...

    A siphon (or syphon) at its simplest is a bent tube, with one end placed in the water to be moved, and the other end into the vessel to receive the water. The receiving vessel must be at a lower level than the supplying vessel. [9] Water will always try to find its lowest level.
