Estimating diffusivity: Simple model

[@ahmedtajir6688]

dear sir could you please add videos of separation process

[@PLE_LU]

I'm having a course on separation processes, but as the course is given in Swedish my next priority regarding KZbin videos is to create some videos in _Swedish_ on porous media, filtration and membrane filtration. After that I'm thinking of revisiting (also in Swedish) preparative chromatography and evaporation. So, sorry, I'm unlikely to be uploading English videos on separation processes in the near future and so far I haven't hear of any such plans from others at our department I have some videos on distillation, however. /Mattias Alveteg (creator of this video and editor of this channel)
