Abstract
Flows over rectangular weirs and the corresponding discharge coefficient Cp are calculated for weirs of various lengths and heights. The fluid is assumed to be incompressible, inviscid, and in irrotational motion in two dimensions with gravity acting. The nonlinear free‐surface conditions are treated exactly. The resulting values of Cp are in good qualitative agreement, and in fair quantitative agreement, with experimentally determined values. Flows over thin weirs and over one triangular weir are also calculated, and a method for any polygonal weir is given.Keywords
