How to find the coefficient of friction of wood on the air?
How to find the coefficient of friction of wood on the air resistance air? Can someone please tell me what the coef. or how to get it? Thank you
The friction model F = mu * N is only applicable to dry friction, involving only the interaction of solid objects. Friction is actually called a drag, if it involves solids interacting with fluids (general term for liquid, gas and other). Drag is a completely different model. Rather than independent of speed, it is definitely dependent on the speed. Two different models exist, depending on the flow regime of the fluid. About more about the drag on the wiki page at: http://en.wikipedia.org/wiki/Drag_ (physics) In addition, resistance forces tend to be independent the type of solid object, with the exception of internal flows (pipes).
