Tailwater velocity
Web14 Dec 2016 · The spillway is 2.50 m high. The upstream face is sloped 1/1. For 60 m3/s, the tailwater rises 1.00 m above the crest. The spillway is designed for the maximum head. 58. OGEE OR OVERFLOW SPILLWAYS 1. Since the spillway is designed for maximum head, HD= He = 1.50 (without the approach velocity head) 2. From the given figure, >2 but <5 59. WebExplanation: The d/s apron is found to have a negligible effect on the coefficient of discharge when the value of (H d + d) / H e exceeds 1.7. where d is the tailwater depth, H d is the design head and H e is the Design head including the velocity head. There can be a decrease in the coefficient due to tailwater submergence.
