What's the difference between siphon and siphonage?
Siphon
Definition:
(n.) A device, consisting of a pipe or tube bent so as to form two branches or legs of unequal length, by which a liquid can be transferred to a lower level, as from one vessel to another, over an intermediate elevation, by the action of the pressure of the atmosphere in forcing the liquid up the shorter branch of the pipe immersed in it, while the continued excess of weight of the liquid in the longer branch (when once filled) causes a continuous flow. The flow takes place only when the discharging extremity of the pipe ia lower than the higher liquid surface, and when no part of the pipe is higher above the surface than the same liquid will rise by atmospheric pressure; that is, about 33 feet for water, and 30 inches for mercury, near the sea level.
(n.) One of the tubes or folds of the mantle border of a bivalve or gastropod mollusk by which water is conducted into the gill cavity. See Illust. under Mya, and Lamellibranchiata.
(n.) The anterior prolongation of the margin of any gastropod shell for the protection of the soft siphon.
(n.) The tubular organ through which water is ejected from the gill cavity of a cephaloid. It serves as a locomotive organ, by guiding and confining the jet of water. Called also siphuncle. See Illust. under Loligo, and Dibranchiata.
(n.) The siphuncle of a cephalopod shell.
(n.) The sucking proboscis of certain parasitic insects and crustaceans.
(n.) A sproutlike prolongation in front of the mouth of many gephyreans.
(n.) A tubular organ connected both with the esophagus and the intestine of certain sea urchins and annelids.
(n.) A siphon bottle.
(v. t.) To convey, or draw off, by means of a siphon, as a liquid from one vessel to another at a lower level.

Siphonage
Definition:
(n.) The action of a siphon.
Example Sentences:
(1) The results of the second experiment suggested that: if the CSF is shunted to the IJV against the direction of blood flow, the ICP will stabilize at a higher level than the VP; blood will not regurgitate into the shunting catheter during periods of rise in the ITP or during changes in posture; siphonage will not develop in the erect posture; the flow of CSF to the IJV will be continuous, and its rate will be equal to and dependent on the rate of CSF formation.
(2) Shunting the CSF in this way prevents the development of siphonage in the erect posture and regulates the intraventricular pressure (IVP) within normal limits.

(8) The results of the first experiment suggested that: if the CSF is shunted to the IJV in the direction of blood flow, the intracranial pressure (ICP) will stabilize at a lower level than the venous pressure (VP); blood will regurgitate into the shunting catheter during periods of rise in the intrathoracic pressure (ITP) and during change of posture from erect to recumbent; siphonage will develop when the erect posture is assumed and will lead to CSF overdrainage and intracranial hypotension; the flow of CSF to the venous circulation will be intermittent.
