Sharp crested weir coefficient
WebbThe flow features over the broad-crested weir with vertical upstream wall and sharp-crested corner are analyzed experimentally. Only the long-crested weir is considered, for which the discharge coefficient remains practically constant. For a relative overflow depth between 10% and 40%, the surface profile, the bottom pressure profile, the boundary … WebbIn general sharp-crested weirs will be used where highly accurate discharge measurements are required, for example in hydraulic laboratories and industry. ...
