looked to me the less viscous plug is subject to increased convection/vortical motion which acts to dissipate energy and increase drag. the more viscous plug is able, on the other hand, to drop like a rigid plug. no slip condition remains valid when one accounts for the tiny air film between the plugs and the wall. Might be useful towards backing out an oil viscosity by measuring drop rates since contact line phenomena (highly phenomenological) are absent?

No lengths were made, this was something observed by physicists not something thats being implemented in this industry. Its pretty likely it doesnât even have any commercial applications. At least not yet.
Just wait till you guys see what ptfe can do at 100c⌠most cart farmer clogs happen at the check valve

Bummer 
I saw it was just a find and not being applied but⌠still kind of exciting? Like ok it wasnât what I envisaged but who cares I just want to smoke!

I dont even use the heater anymore. I just warm it up as I go with the heat gun. It doesnât take much to keep it flowing.

WOW it is cheap too!!!

it is harder than ptfe too, goes nice in compression/push to connect fittings.

exactly no slip condition. theyâre really playing around w/ the boundary layer, this is super fucking interesting yet seems so simple
fluids was my research bread and butter but Iâve given up hopes of whipping out nonlinear PDEs in hempworld. For now at least
