n channel with bottom and sides of averagerubble masonry and whose depth h is to be one-half of itswidth is to conduct a water-supply of Q = 120 cub. ft. per sec.with uniform motion, with a fall of only 3 ft. in its lengthof 1200 ft. Compute a proper value for the depth h. SeeFig. 101. A is the… … Fig. 101. (see §132); and the slope is 3 -s-1200 = 0.0025, Lei, 2.5 ft.per thousand; but as the value of R is as yet unknown, it isimpossible to use the diagram directly for finding the valueof Kutters coefficient A. Since the values of A, however, range between 65 and150 for ordinary cases, a…
