Water flowing along a channel meets a constriction so that the water surface at the constriction dips relative to the upstream level as shown in the figure below. For a given flowrate Q = 1.2 m3/s, calculate all possible solutions for y2, where y1= 2m, bị, = 1m, b2 = 0.5 m. Find the value for the velocity uz that corresponds to the solution that best matches the figure below. The flow is steady and you can neglect frictional losses in the channel. Тор Side
