New relationships have been developed for the contraction coefficient, based on analysis that shows that the pressure distribution on the gates is … WebContraction and expansion losses are based on a coefficient times the change in velocity head. Guidance on the selection of contraction and expansion coefficients has also been provided in "Basic ... For the first case (see the figure below), a sluice gate type of equation is used (FHWA, 1978): 1) \displaystyle Q=C_d A_{BU} \sqrt{2g} \left[ Y_3 ...
WebThe channel the longitudinal section of which is shown in Figure Q3 has a Manning's coefficient of 0.013, a slope of 0.001 and may be assumed to be wide. Reaches between all possible control features are sufficiently long for uniform flow conditions to become established. The coefficient of contraction of the sluice gate is 0.61.
WebSluice‐gate discharge coefficient is an involved function of geometric and hydraulic parameters. For free flow, it is related to upstream depth and gate opening, whereas for submerged flow, in addition to these parameters, it depends on tail‐water depth.
