As shown in Fig. P5.22, at the entrance to a 3 -ft-wide channel the velocity distribution is uniform with a velocity \(V\). Further downstream the velocity profile is given by \(u=4 y-2 y^{2}\), where \(u\) is in \(\mathrm{ft} / \mathrm{s}\) and \(y\) is in \(\mathrm{ft}\). Determine the value of \(V\).
