Water enters a two-dimensional, square channel of constant width, \(h=75.5 \mathrm{~mm}\), with uniform velocity, \(U\). The channel makes a \(90^{\circ}\) bend that distorts the flow to produce the linear velocity profile shown at the exit, with \(V_{\max }=2 V_{\min }\). Evaluate \(V_{\min }\), if \(U=7.5 \mathrm{~m} / \mathrm{s}\).
