Excerpt from Sullivan's New Hydraulics, Consisting of New Hydraulic Formulas and the Rational Law of Variation of Coefficients: Flow and Resistance to Flow in All Classes of Rivers, Canals, Flumes, Aqueducts, Sewers, Pipes, Fire Hose, Hydraulic Giants, Power Mains, Nozzles, Reducers, Etc, , With Extensive Tables and Data of Cost of Pipes and Trenching and Pipe Line ConstructionThe loss of head or pressure by resistance as computed by the ordinary formulas is much too small in small pipes and greatly in excess of the truth in large pipes. The reason of these erroneous results is that the coemcients were deter mined for pipes of medium diameter and do not vary correctly so as to meet the requirements of varying diameters. Hence the greater the diameter varies from the medium, either be low or above, the greater will be the error in the computed result. The usual formulas for ¿ow in Open channels are equally faulty, but not in the same way.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
