Bodies with various cross-sectional shapes subjected to cross-flow of air are shown in the following figures. The characteristic dimension of all the shapes is the same. The cross- sectional shape with the largest coefficient of drag (i.e. sum of the pressure and skin- friction drags), at any moderately large Reynolds number, is
