Reynolds Number - Laminar and Turbulent Flow

"Before I die, I hope that someone will explain quantum mechanics to me. After I die, I hope that God will explain turbulence to me." - Werner Heisenberg

I am calling bs on this one. The "reverse" flow was just them playing the video in reverse.

@jrizzlehhi24 nope.. i thought the same thing. but looked at the finger positions on the handle.. forward doesn't match up with "reverse"

[leifdenby]

@jrizzlehhi24 look at the hands of the person to the right. Their finger changes position between the forward and reverse direction. Making it hard to believe that they've run the video in reverse, since their fingers would then be in the same position.

... definitey a bong at 3:35

what was the container called u stired them in called

Thanks!

amazing. never thought that was possible, to reverse the dye concentration

[lethalbizzle078]

great video though in Reynolds equation, D is for diameter (or hydraulic diameter if the pipe isnt cylindrical)

very good, strange how the dye goes back to how it was
