siphonn.

/ˈsʌɪfən/

Forms: Also 1600s–1700s cyphon, 1600s– syphon.

Etymology: < Latin sīphōn-, sīpho (compare sipho n.), < Greek σίϕων pipe, tube. Compare French siphon (1611), Spanish sifon, Portuguese sifão, Italian sifone.

a. A bent pipe or a length of flexible tubing placed with one end in a container of liquid and the other end outside it at a lower level, with the aim of conveying liquid upwards from the container and out from the lower end of the pipe or tube.The way the action of the siphon is explained has varied. A common explanation is that atmospheric pressure acts on the liquid in the upper container to push it into the tube as gravity pulls downwards the liquid in the lower length of tubing (so that a vacuum would otherwise form in the space vacated). Recently the rise of the liquid in the ‘up’ tube has been attributed to the cohesiveness or tensile strength of the moving liquid rather than to atmospheric pressure: the falling liquid in the ‘down’ arm in effect drags or pulls that in the ‘up’ arm. The following quotations illustrate the varying explanations.

1675 J. Wallis Disc. Gravity & Gravitation 35 The like account we give of the Syphon. The Pressure on A, (in Fig. 35.) will raise the Fluid to the height of B, if not greater than what is before described; and from thence to O, it falls by its own Weight.

1683 G. Sinclair Nat. Philos. 45 From this experiment we see first, that the Pressure of the Air, is the proper cause of the motion of Water, up thorow Pumps and Siphons.

1864 Jrnl. Franklin Inst. 78 29 According to Hero, a liquid rises in one leg of a siphon when suction is applied to the other, because when we have sucked out the air we become fuller than before, pressure is exerted on the air near us, it is communicated to the liquid in which the siphon is immersed, and compels it to rise in one leg of the instrument to fill the void space therein.

1913 Domest. Engin. (Chicago) 1 Feb. 130/2 To start the siphon, the air in the long arm must be exhausted. As soon as this vacuum is formed, atmospheric pressure exerted on the surface of the liquid will force the liquid up through the short arm..and into the long arm.

1971 Physics Educ. 6 362 Few books point out that it is the cohesion of the liquid rather than the pressure of an external atmosphere which is crucial to the working of a siphon.

2008 M. Kay Pract. Hydraulics (ed. 2) iv. 96 Atmospheric pressure drives a siphon and the absolute limit is 10 m head of water.
