Table 
-For Estimating the Capacity of Glazed Conxeete 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, A , in square feet.
