Compute the discharge over a Cipolleti weir 5.0 ft long under a head of 0.85 ft. Compare with the discharge over a standard rectangular weir with the same length and head.

Find the discharge over a 75 degree V-notch weir if H = 6 inches

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.
