THE FLOW OF WATER IN CONCRETE PIPE. 



61 



Table 9.— For Estimating the Capacity of Glazed Concrete Pipe Lines— Continued. 



For instance, 400 second-feet of water, the equivalent of 259 million United States gallons per day, will be 

 conveyed by a 120-inch pipe at a velocity of 5.09 feet per second with a loss of head (grade) of 0.48 foot 

 per thousand feet of pipe. 





Inside diameter in inches and corresponding area, 4 , in square feet.
