Based on formula V— CsIP^d -^ using 0.370 for the coefficient C 5 For instance, 140 second-feet of water, the 

 equivalent of 90.5 million United States gallons per day, will be conveyed by a 54-inch pipe at a velocity 

 of 8.80 feet per second with a loss of head (grade) of 3.86 feet per thousand feet of pipe. 







Inside diameter in inches and corresponding area, A ,
