288 HYDRAULICS AND ITS APPLICATIONS 



by a syphon is 25 feet. The length of the syphon is 2,000 feet and its 

 diameter is 12 inches. Assuming /= '005, and that the syphon runs 

 full, determine the discharge. Also if the vertex of the pipe line is 

 16 feet above the surface level in the upper reservoir, determine the 

 maximum length of inlet leg for the pipe to run full. Neglect all but 

 friction losses. 



Answer. Q = 4*99 c.f.s. 



= 1,865 gallons per minute. 

 Maximum length of inlet = 1,440 feet.
