ETYM French siphon, Latin sipho, -onis, from Greek siphos a siphon, tube, pipe.
Tube in the form of an inverted U with unequal arms. When it is filled with liquid and the shorter arm is placed in a tank or reservoir, liquid flows out of the longer arm provided that its exit is below the level of the surface of the liquid in the tank.
It works because the weight of liquid in the short arm is less than that in the long arm. This produces an imbalance of pressure which tends to force the liquid from the tank up the short arm.
A tube running from the liquid in a vessel to a lower level outside the vessel so that atmospheric pressure forces the liquid through the tube; SYN. syphon.
