	<span lang=\"EN-US\">This paper present the effect of the lower gate lip on the coefficient of contraction, velocity and discharge which have been made in a rectangular flume with four gates opening from (2 to 4.5) cm, five different discharges from (6.2 to 18.15)</span><span lang=\"EN-US\"> </span><span lang=\"EN-US\">l/s and five different gate cases (vertical and inclined vertically) by angle </span><span lang=\"EN-US\">(</span><span lang=\"EN-US\">45</span><span lang=\"EN-US\">)¡ã </span><span lang=\"EN-US\">with and opposite flow direction with horizontal and sharp lower lip.</span><span lang=\"EN-US\"> </span><span lang=\"EN-US\">The values of coefficients of contraction (C<sub>c</sub>) and discharge (C<sub>d</sub>) increases when gate slope increases with flow direction and the lower lip is horizontal, these increases are (16</span><span lang=\"EN-US\">)</span><span lang=\"EN-US\">% and (18</span><span lang=\"EN-US\">)</span><span lang=\"EN-US\">%</span><span lang=\"EN-US\"> </span><span lang=\"EN-US\">respect</span><span lang=\"EN-US\">tively, while these values decreases when gate slope increases opposite flow direction and the lower lip is horizontal these decreases are (13</span><span lang=\"EN-US\">)</span><span lang=\"EN-US\">% and (11</span><span lang=\"EN-US\">)</span><span lang=\"EN-US\">% respectively.</span><span lang=\"EN-US\"> </span><span lang=\"EN-US\">The values of coefficient of velocity (C<sub>v</sub>) remain constant and don¡¯t effect with changes of gate slope or gate lip.</span>
