Abstract

Submerged rectangular orifice is among discharge measuring device which is suitable in small canal especially when the amount of fallis not adequat for application of weir, during the past decade many study have been conducted for evaluation of discharge coefficient of orifice. For free the case of submerged orifice only an average value of 0.61 has been mentiond in the literature. Since this coefficient depends to the flow characteristics and the orifice dimensions, an equation for determination of discharge coefficient is needed. The development of such formula is the main goal of this study. To do so an experimental program was conducted and applying the dimensional analysis and data obtained from these tests, one relation was developed. This relation can be used where an accurate value of the discharge coefficient and consequently the flow discharge is needed.
