Halving the wetted area of a streamlined body while holding the friction coefficient fixed changes its friction drag by a factor of
Answer: D
Friction drag is proportional to wetted area at a fixed coefficient, so halving the area halves the drag. This linearity is why reducing wetted area is such a direct lever on a streamlined body, where friction rather than pressure drag dominates.
