I am sure there are those who could calculate all the relative data. Not sure it is us . We know from fluid dymanics that the drag is proportional to the density of the fluid and proportional to the square of the speed. I guess we would need the reynolds number of the projection before expansion......

Ah, better get your calculus book out
Texas, I luv u
