Chapter 10, Problem p10.116(choose chapter or problem)
A Cipolletti weir, popular in irrigation systems, is trapezoidal, with sides sloped at 1:4 horizontal to vertical, as in Fig. P10.116. The following are fl ow-rate values, from the U.S. Dept. of Agriculture, for a few different system parameters: H 4 1 1 4 b P10.116 H, ft 0.8 1.0 1.35 1.5 b, ft 1.5 2.0 2.5 3.5 Q, gal/min 1620 3030 5920 9740 Source: U.S. Dept of Agriculture. Use this data to correlate a Cipolletti weir formula with a reasonably constant weir coeffi cient.
