Question

what is viscous drag.?

Answer 1

If a fluid in laminar flow flows around an obstacle, it exerts a viscous drag on the obstacle. Frictional forces accelerate the fluid backward (against the direction of flow) and the obstacle forward (in the direction of flow). The viscous drag force increases linearly with the speed of the fluid.

Answer 2

Viscous Drag. If a fluid in laminar flow flows around an obstacle, it exerts a viscous drag on the obstacle. Frictional forces accelerate the fluid backward (against the direction of flow) and the obstacle forward (in the direction of flow). The viscous drag force increases linearly with the speed of the fluid.
