i don't think it's a linear extrapolation.
Chip is the wrong descriptor.
The 1/32-1/16" thick ripped strips and end grain thingies that come off the table and miter saw, and long, curly Forstner bit waste are what had me pull out the grounds.

Then there's the lathe.
No so fast there.
Because of the velocity distribution you describe for pneumatic transfer of suspended solid particulate matter,e.g. dust collection, turbulent is good and laminar is bad. That is because the turbulence will keep the dust suspended in the air, but laminar flow will allow it to drop out and accumulate in the ducts. Or more realistically, the laminar flow wouldn't pick up much dust in the first
place.
