Re: dressing up a problem

Which is another way of saying that the velocity dependence of the drag
force isn't a simple power law over any appreciable range of speeds. The
"drag coefficient" is often only slightly better than an empirical fudge
factor behind which all of the overly difficult fluid dynamics is hidden.
