A general formula for the uniform flow of water in rivers and other channels; by E. Ganguillet and W.R. Kutter. Tr. from the German, with numerous additions, including tables, diagrams, and the elements of over 1200 gaugings of rivers, small channels and pipes, in English measure (1889)

he above figure, as ordinates, as in Fig. 18, then, in orderto express the variation of c with the variation of the slope inthe formula, as explained in our treatise, we draw a straightline as nearly as practicable through the points obtained, andextend it to the axis of ordinates. The equation of… … the axis of abscissa from the intersection of the straight line with the axis of ordinates. Since -^, at the origin of the axis of abscissae, is = o, r, corresponds to a slope 5 = co . The varia-tion of c with variation of slope may therefore be expressed in the general equation c = y X I + —= ^ VR…
