Talk:803: Airfoil

Since gases are unique in the way they convert pressure change to heat or cold, none of the above can be true. The schema shows more columns of air under the wing than pass above. How come? We know that an actual wing pulls air down from the layers above rather than bludgeon the air in front of it.
What happens is that vortices are engendered. Wing design is all about getting them past the control sections (the major problem to aircraft design in the 1940's.) I used Google News BEFORE it was clickbait (talk) 01:15, 26 January 2015 (UTC)
It is a convention in fluid dynamics that the flow always comes from the left. Nobody working in this field would ever draw a picture with the flow coming from the right side. So this is a hint by its own that the image may be wrong.
Regarding the last comment: The image is from wikipedia. The original comment tells us that the wing influences the flow even at a great distance. The flow at the top is still a lot faster than below the wing.

My high school math teacher said there were three ways for a teacher to say "I don't know" -- "I don't know", "It's beyond the scope of the course", and "You wouldn't understand it if I told you." So, whenever we asked a question like the one in the comic, he'd say "It's beyond the scope of the course, and you wouldn't understand it if I told you anyway! Dumb kids!" We loved that guy. 172.68.189.181 17:01, 5 July 2018 (UTC)
This airfoil problem is a 2D problem and the classical Bernoulli's equation is a 1D equation. If you use velocity vector(speed and direction) instead speed the equation works.
I suspect most school children have seen a paper airplane, maybe even built one. Those wings are, for practical purposes, 2D. Nitpicking (talk) 15:56, 6 March 2023 (UTC)dead
I feel like Miss Lenhart's head looks... squarer in the last panel. Xkdvd (talk) 01:46, 20 February 2026 (UTC)
- 'Early' comic, relatively ('only' five years into the comic, fifteen more years having passed since then; and only the eighth comic of 38 (currently) marked as featuring Miss L). Given the style, could just be a minor mis-sweep of the chin/hair curves. Less practiced than several more years down the line, and/or less likely to be undone/wiped and redrawn 'better' with a far more self-critical/perfectionst eye.
- Could also be an attempt at expression/attitude change (sometimes you get a hint of this from the exact tilt, or skew, of even an otherwise featureless Cueball-head 'loop', if that's not just in the eye of the beholder), but I don't think there's enough to suggest a deliberately invoked 'squaring of jaw' intent here, given that this alone does not easily account for the changed line of her hair on the back and top of her head/etc. 82.132.239.77 14:04, 20 February 2026 (UTC)
