Repeat Problem 10.16 if the upstream depth is y₁=0.5 ft. Assume that there are no losses between sections (1) and (2).

Problem 10.16

Water in a rectangular channel flows into a gradual contraction

section as indicated in Fig. P10.16. If the flowrate is Q = 25 ft³/s and the upstream depth is y₁ = 2 ft, determine the downstream

depth, y₂.
