Oil (absolute viscosity \(=0.0003 \mathrm{lb} \cdot \mathrm{s} / \mathrm{ft}^{2}\), density \(=50\) \(\mathrm{lbm} / \mathrm{ft}^{3}\) ) flows in the boundary layer, as shown in Fig. P1.82. The plate is \(1 \mathrm{ft}\) wide perpendicular to the paper. Calculate the shear stress at the plate surface.
