Syphon is a long bent pipe which is used to transfer liquid from a reservoir at a higher elevation to another reservoir at a lower level when the two reservoir are seperated by a hill or a high level ground as shown in figure.
The point c is at the highest of the syphon is called the summit.As the point C is above the free surface of the water in the tank A, the pressure at C will be less than atmospheric pressure.Syphon is used in the following cases
- to carry water from one reservoir to another reservoir seperated by a hill or ridge.
- to take out the liquid from tank which is not having any outlet.
- to empty a channel not provided with any outlet sluice.
