love the video man

"Duke it out" makes it sounds like they have equal footing.
-
really informative and interesting
-
@Quintinohthree I took the course in fluid mechanics last semester and when calculating Reynold's no. we used Re = (rho x velocity x dia.)/mu. So, I guess that's why he uses radius here, because he is using kinematic viscosity and we used dynamic viscosity. Just realised that haha.
-
How so? If you'd use the diameter you'd just get a number twice as big so you can do your calculations either way you'd just have to correct other formulas for this.
-
Not very interesting: fluids have viscosity. Fluids travel through a tube at a velocity. Flow rate is also dependent on tube diameter. At a certain velocity, turbulence ensues. Big f'n deal.
-
@manalokos nearly any dynamic analysis on liquid flow
-
Surely he meant Diameter, not radius?
-
he professor Laurence Eaves.

@ 1:05 "you can see this got a diameter" Such an obvious observation sounds enigmatic coming from a phisicist....I feel like I'm missing some clue here. LOL

Seriously, this is a video about fluid dynamics, not an argument forum for creationists and evolutionists to duke it out. If you really feel that compelled, go find someplace else to have your arguments and let everyone else enjoy the videos.

If only my science teachers had been more like Professor Eaves and less like nodding versions of Ben Stein... sigh..
The Sixty Symbols team has made science FUN again!
