Which of the following factors affects skin friction drag?

Question

Quizplus · Accepted Answer

Skin friction drag is affected by all of the above factors. A higher relative velocity of fluid flow means there is more turbulence and mixing happening, leading to increased skin friction drag. The surface area of the body over which the flow occurs directly impacts the amount of surface contact that the fluid has with the body, leading to increased skin friction drag. Finally, the viscosity of the fluid determines the internal resistance of the fluid flow, which can result in increased skin friction drag.
