Abstract
A theoretical analysis and hydraulic experiments were performed to investigate the head loss that occurs when a flow passes through a perforated wall with vertical slits. In the theoretical analysis, continuity and energy equations were applied to a control volume set near the perforated wall. A non-dimensional energy equation was then derived to calculate head loss for the given values of the ratio of upstream and downstream depths and a Froude number based on downstream depth and velocity. The hydraulic experiments were performed by varying flow condition and the opening ratio of perforated walls. The non-dimensional energy equation and experimental results were finally used to evaluate the accuracy of three existing formulas.
