Assume laminar boundary-layer flow to estimate the drag on four square plates (each 3 in. \(\times 3\) in.) placed parallel to a \(3 \mathrm{ft} / \mathrm{s}\) water flow, for the two configurations shown. Before calculating, which configuration do you expect to experience the lower drag? Assume that the plates attached with string are far enough apart for wake effects to be negligible and that the water is at \(70^{\circ} \mathrm{F}\).
