When is there a 1. order relationship between velocity and drag, and when is it 2. order? And why is there a difference, and why 1. and 2. order and not 3. or 4. ?
I know that when the velocity is low the relationship is 1. order and when the velocity is high it becomes 2. order. But I don’t know where the limit is.
Can anyone help?
Cheers.
