Coefficient Of Discharge For A Combined Hydraulic Measuring Device (original) (raw)

This study explores the coefficient of discharge (Cd) for a newly designed combined hydraulic measuring device that consists of a rectangular weir and a semi-circular gate. Nine models were constructed to assess how variations in gate width and flow position affect Cd. Experimental results indicate that Cd increases as the ratio of d/h increases, and also with wider gate widths. The study presents a multi regression model to estimate Cd with a 10% margin of error, providing useful insights for applications in flow measurement across canals, rivers, and reservoirs.
