Analysis of Flow through Lateral Slot

Analysis of diversion of flow has received considerable importance in existing literature. In this study, diversion of flow through a lateral slot is analyzed using the spatially varied flow equation and the elementary discharge coefficient function. The implications of treating flow through a side slot as through a small orifice, as reported in the literature, are also studied. For different combinations of slot openings and sill heights, data for a set of 110 runs have been obtained. Using these experimental observations, equations for the elementary discharge coefficient are obtained for small as well as large orifice formulations of flow through a lateral slot. The elementary discharge coefficient is mainly dependent on slot geometry. Using the developed expressions of the elementary discharge coefficient, it is shown that more than 90% of the data are represented within an error band of ±10%.
