Relative velocity of the fluid affects which of the following?

Question

Quizplus · Accepted Answer

All of the given options are affected by the relative velocity of the fluid. Skin friction is the drag force that appears on the surface of an object due to the movement of a fluid past the object. The wave drag is another kind of drag force that is generated due to the waves that form at the interface between the fluid and the body as a result of their motion. Lastly, lift force is the force that acts perpendicular to the direction of fluid flow on an object moving through the fluid. All of these forces are dependent on the relative velocity of the fluid and hence are affected by it.
