Page 5 - indicated that the resistance offered by the perimeter of a channel is represented by two values, the first of which is proportional to the velocity and the second to the square of the same. Upon this principle de Prony based his
Page 9 - observed by others, that those pipes which presented the smoothest inner surface furnished the greatest quantity of water in a given time ; or in other words, that the greatest velocity was found in the smoothest pipes. He argued
Page xi - A number of authors have endeavored to establish laws for its variation, and among them Ganguillet and Kutter appear so far to have been the most successful.
Page 4 - that the resistance is independent of the weight or pressure of the water, so that its friction upon the walls of pipes and channels is entirely different in its nature from that existing between solid bodies.
Page 110 - The coefficient of resistance or roughness (») can be found only by consulting cases where analogous physical conditions prevail, and for which its value has already been ascertained.
Page 54 - not only the mere roughness of the surface, but also the irregularities and imperfections (Schadhaftigkeit) in the bed of the channel or river.
Page 4 - summed up in these two laws: 1. The force which sets the water in motion is derived solely from the inclination of the
Page 4 - 2. When the motion is uniform the resistance which the water meets, or the retarding force, is equal to the accelerating force.
Page x - limited to cases where the slope of the water-surface can be ascertained with a degree of accuracy sufficient for the given case.
Page 117 - v = 3.03 ft. per sec. Assume a slope (say .0001). Find its curve, and radial line n = .03. Join their intersection with R = 20, and note the value (89) of c where
