WebbThe sharp crested weir was widely used to compute the flow discharge (M. Piratheepan et al., 2006). The sharp crested were divided into three types which are rectangular weir, V-notch weir and trapezoidal weir. In this analysis, the rectangular sharp crested weir was choosing as the regulator. WebbThe Francis formula for the discharge of a sharp-crested rectangular weir having a length b greater than 3h is Formulas 1.0 Q = 3.33 ( ( b - n · h ) / 10 ) [ ( h + ho )3/2 - ho3/2 ] Where: Q = discharge over weir, ft 3 /s (m 3 /s) b = length of weir, ft (m)
