THE FLOW OF WATER IN WOOD-STAVE PIPE. 
69 
Table 7. — Velocity V in feet per second and loss of head H in feet per thousand feet 
of pipe, necessary to the conveyance of a given quantity of water, Q, in second^feet 
and in millions of U. S. gallons per day through wood-stave pipe, based on formula 
H= 
7.68 V 1 - 
For instance, 5 second-feet will be carried by a 16-inch pipe at a 
velocity of 8.58 feet 
per second with 
a loss of head of 2.98 per 
thousand feet of 
pipe.
