The term "siphon" is used for a number of structures in human and animal anatomy, either because flowing liquids are involved or because the structure is shaped like a siphon, but in which no actual siphon effect is occurring: see Siphon (disambiguation). There has been a debate if whether the siphon mechanism plays a role in blood circulation ...
Thermosyphon circulation in a simple solar water heater (not a working model; there is no water supply to replenish the tank when the tap is used). A thermosiphon (or thermosyphon) is a device that employs a method of passive heat exchange based on natural convection, which circulates a fluid without the necessity of a mechanical pump.
A Soxhlet extractor has three main sections: a percolator (boiler and reflux) which circulates the solvent, a thimble (usually made of thick filter paper) which retains the solid to be extracted, and a siphon mechanism, which periodically empties the condensed solvent from the thimble back into the percolator.
Cross section of a Pythagorean cup being filled: at B, it is possible to drink all the liquid in the cup; but at C, the siphon effect causes the cup to drain. A Pythagorean cup looks like a normal drinking cup, except that the bowl has a central column in it, giving it a shape like a bundt pan. The central column of the bowl is positioned ...
In organic chemistry, neighbouring group participation (NGP, also known as anchimeric assistance) has been defined by the International Union of Pure and Applied Chemistry (IUPAC) as the interaction of a reaction centre with a lone pair of electrons in an atom or the electrons present in a sigma or pi bond contained within the parent molecule but not conjugated with the reaction centre.
The chain fountain phenomenon, also known as the self-siphoning beads, Mould effect, or Newton beads is a physical phenomenon observed with a chain placed inside a jar. One end of the chain is pulled from the jar and is allowed to fall under the influence of gravity .
Jan 7, 2025; Charlotte, North Carolina, USA; Phoenix Suns center Jusuf Nurkic (20) reacts after being called on a foul during the second half against the Charlotte Hornets at the Spectrum Center.
A picture of a bottle with a gas inlet is shown in the works of Mariotte, [1] but this construction was made to show the effect of outside pressure on mercury level inside the bottle. It further misses a siphon or an outlet for the liquid.
