Assume laminar boundary-layer flow to estimate the drag on the flat plate shown when it is placed parallel to a \(15 \mathrm{ft} / \mathrm{s}\) air flow. The air is at \(70^{\circ} \mathrm{F}\) and \(1 \mathrm{~atm}\). (Note that the shape is given by \(x=y^{2}\), where \(x\) and \(y\) are in feet.)
