VALUES OF COEFFICIENT CO 4.0 3.8 3.2 3.0 40 0.5 1.0 1.5 VALUES OF 0=COL H 2.0 3 3.0 1) - A) For free-flowing chute spillway with discharge capacity of 2000 m3/s and crest width of 100 meters, and zero depth of approach(P), what would be the depth of water (Ho) passing over the chute? -B) If depth of approach is set at 8 meters, how many percent crest width is reduced, for the same water depth over chute? - C) if spillway arrangement in (B) is replaced by gated type arrangement shown here, with 6 meter high gates and T=8 meter; C.1) What would be discharge capacity at full gate opening. C.2) What would be the percentage of gate opening for 2000 m3/s discharge. N Zj T H ZD B Zsp Note: i) For discharge calculations in free flowing and gated spillway, see equations in Chapter 5, Spillway (section 5.6) ii) In equation for gated spillway (part "C") calculation assume: C=0.75, T=8m, H=6m, TE=0.16, BE=0.72, HE= 0.62 iii) Note that equation given for discharge in gated spillways are in British Unit".
