Question

Approximation for rotational drag on a box?

Answer 1

The drag equation gives us an approximation for the drag on an object caused by its velocity in a fluid:

F=12ρAv2Cd
Is there any similar approximation for the rotational drag on an object caused by its angular velocity? I am particularly concerned with boxes (rectangular prisms), but would also be interested in a more general approximation, if one is available. Thanks!

Hope this helps you ✌️ ✌️ ✌️....
