Siphoning is used to pump a fluid from one place which is at a higher elevation to another without any external equipment. Initially the fluid flows to a higher elevation from the beaker or reservoir containing the fluid and then flows downward. Atmospheric pressure and gravity both are necessary for siphoning to work. Although siphoning also works in vacuum for fluids that have strong cohesive bonds such as mercury. Siphoning has a maximum limit for the height up to which a fluid can be lifted depending on the atmospheric pressure, density of the fluid and gravity. The maximum height up to which water can be siphoned on Earth is 10.32 m.
