Table 7 (Continued). — 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. For in- 
stance, 550 second-feet will be carried by a 120-inch pipe at a velocity of 7 feet per second 
with a loss of head of 0.94 foot per thousand feet of pipe.
