This series shows many interesting characteristics of drag. Especially interesting in the 4th video about the round versus pointy shapes. I like the round shapes with the rough surface also. Looks like everyone should definitely be working on the back ends for most gains.
Wanted to thank you for ferreting this stuff out of You-Tube.It's worth millions of words.Priceless!
It would have been nice to have been exposed to this sort of thing in high school.
Perhaps we at EcoModder can make up for lost time.
Again,thanks!
