Head-discharge relationshipOne of the contributing factors to the poor performance of irrigation systems is improper water distribution. Traditionally, in irrigation canals water distribution schedules are determined based on descriptive methods. Application of optimization methods could improve performance of ...
Discharge coefficients When an orifice proving report was calculated, the empirically derived massdischarge coefficientwas compared with two empirical predictions—the Stolz andBuckinghamequations. The Mass Discharge Coefficient was calculated from the master meter proving results using the following formula: ...
