Unformatted text preview: siphon, and the headwater elevation is 0.6 m above the summit. Assuming coefficient of discharge of 0.9, what is the capacity of the siphon? What head would be required on an ogee spillway (C w = 2.15) 3.0 m long to discharge this flow? What length of ogee weir would be required to discharge the same flow as the siphon with a head of 0.6 m on the weir crest? 9.11) Water flows over the ogee section of a low diversion dam 6 ft high at a rate of 15 cfs/ft of spillway length. The flow regime is like that of Fig. below. The spillway coefficient is 3.6 and the tailwater depth is 3.0 ft. Find the net force in the horizontal direction exerted by the water per unit length of this spillway. How will it change if the tailwater depth drops to 2.5 ft? 9.23) What will be the depth after hydraulic jump in a horizontal rectangular channel 12 ft wide when the flow rate is 350 cfs and the depth of flow before the jump is 2.1 ft?...
