86. THE SIPHON 



The siphon consists of a bent tube with one leg effectively 

 longer than the other. If such a tube is placed in a dish of 

 water, with the longer leg outside, and the whole tube is filled 

 with water, the water in the longer leg will run out. This tends 

 to produce a vacuum in the tube, which is prevented by the 

 atmospheric pressure, acting on the surface of the water and 

 pushing it up the short leg of the siphon. Thus there is a 

 continual flow of water. Unless the surface of the liquid in 

 the dish is open to the pressure of the air, the siphon will not 

 flow. The longer the long leg, the faster the water will flow 

 through the siphon.
