The following data are obtained for a particular reach of the Provo River in Utah: \(A=183 \mathrm{ft}^{2}\), free-surface width \(=55 \mathrm{ft}\), average depth \(=3.3 \mathrm{ft}, R_{h}=3.32 \mathrm{ft}, V=6.56 \mathrm{ft} / \mathrm{s}\), length of reach \(=116 \mathrm{ft}\), and elevation drop of reach \(=1.04 \mathrm{ft}\). Determine

(a) the average shear stress on the wetted perimeter,

(b) the Manning coefficient, \(n\), 

(c) the Froude number of the flow.
