Question

Viscous drag on a spherical body is indepentdent of

Answer 1

hlo mate ✌️

Drag force is proportional to the velocity for a laminar flow and the squared velocity for a turbulent flow. Even though the ultimate cause of a drag is viscous friction, the turbulent drag is independent of viscosity. Drag forces always decrease fluid velocity relative to the solid object in the fluid's path.

Hope it helps.
