Prediction of the discharge coefficient for the rectangular notch with different hydraulic and geometric properties

Abstract This study aims to investigate experimentally the variation of coefficient discharge Cd with rectangular notch hydraulic and geometric parameters such as water head h, height p, width B, thickness t. The results show that increases an increase h B while it decreases There are no changes in actual Qact consequently for p more than 6 cm. An empirical formula was developed based on dimensional analysis principle can be used predict value known data (h, t).
