A rectangular, sharp crested weir with end contraction (Effective width B’= 1.6-0.2H m), where, H is head over the weir. How high (P), crest should be placed in a channel to maintain upstream depth of 2.5 m (P+H) and discharge through the weir is 0.5 m3/s. You could neglect approach velocity for this problem and assume Cd= 0.62 (5 points). V? a Drawdown 28 Nappe y2 H 28 Va Crest P V
