THE FLOW OF WATER IN CONCRETE PIPE. 
57 
Table 
7.— For Estimating the Capacity of Modern "Wet-Mix 
Monolithic Concrete Pipe Lines. 
Jointed and Well-Made 
Based ou fcrmula V= Cs 7I - 5 d - 625 using 0.345 for the coefficient C s . For instance, 3 second-feet of water, 
the equivalent 
of 120 miner's 
inches of tvpe 
A or 150 inches of type B 
, will be conveved bv a 16-inch 
pipe at a velocity of 2.15 feet per second with a loss of head (grade) of 1 
22 feet per th 
ousand feet of pipe. 
Quantity (Q). 
Inside diameter in inches and corresponding area, A, in square feet.

1 Columns headed A(40) and B(50) respectively refer to the number of miner's inches in the equivalent 
number of second-feet. For instance, 72 miner's inches are the equivalent of l.S second-feet in communities 
where 40 inches equals 1 second-foot.
