A flat plate \(1.5 \mathrm{~m}\) long and \(0.3 \mathrm{~m}\) wide is towed at \(3 \mathrm{~m} / \mathrm{s}\) in a towing basin containing water at \(20^{\circ} \mathrm{C}\), and the drag force is observed to be \(14 \mathrm{~N}\). Calculate the dimensions of a similar plate that will yield dynamically similar conditions in an airstream \(\left(101.4 \mathrm{kPa}\right.\) and \(\left.15^{\circ} \mathrm{C}\right)\) having a velocity of \(18 \mathrm{~m} / \mathrm{s}\). What drag force may be expected on this plate?
