Question

Show all working for the question please. The numerical solutions are attatched as well.

Solution: Upstream of the gate, the flow conditions associated with a reduction in discharge correspond to the formation of a positive surge. Numerical solution: Vsrg = 3.97 m/s, V₂ = 0.33 m/s, d₂ = 2.25 m
