A sharp-crested suppressed rectangular weir 1m long and a standard 90- degree V-notch weir are placed in the same weir box with the vertex of the V- notch weir 150mm below the crest of the rectangular weir. Determine the head on the rectangular weir. Determine the head on the rectangular weir when their discharges are equal. Use Francis Formula.

A contracted from the two ends sharp-crested weir is installed in a channel and has a crest heigh of 7.2 m and a crest effective length of 4 m. The discharge coefficient (Cd) is 1.81. At design flow, a 1.1 m static head develops upstream of the weir. Determine the crest height of a non- contracted-90°-V-notch (replacement) weir with Cd =2 that would discharge the same design flow rate without raising the upstream flow depth in the channel. Y
A circular settling basin is anticipated to receive a flow of 3.5 MGD. The tank is to be designed to have an overflow rate of 800 gpd/ft2. The depth is to be 11 ft. Determine the diameter of the basin (in feet). ? What length of weir (ft) is required to achieve a weir loading of 15,000 gpd/ft show all work
Choose the letter of the correct answer. Please answer honestly and do not just guess. Develop a formula for the discharge over a 90° V-notch weir in terms of head above the bottom of the V. A channel conveys 300 litres/sec of water. At the outlet end there is a 90° V-notch weir for which the coefficient of discharge is 0.58. At what distance above the bottom of the channel should the weir be placed in order to make the depth in the channel 1.30m? a. 0.759 m c. 0.769 m b. 0.749 m d. None of the above From above question, with the weir in this position what is the depth of water in the Cchannel when the flow is 200 litres/sec? a. 1.218 m b. 1.212 m c. 1.232 m d.
