Excuse me, in the last part you mentioned that Chilton Colburn's analogy says nothing about the diffusivity of mass, heat and momentum. But in the Chilton-Colburn analogy there are Pr or Sc (jH or jD) which are relations of diffusivities ... could clarify this for me. Your videos are very interesting. Thank you very much!
Hi, yes I was simplifying so much that I became a bit unclear there, I think the video on Reynolds analogy and Chilton Colburns analogy is clearer: ruclips.net/video/7YlQ_4jL_gs/видео.html In Reynolds analogy there is no connection at all between transfer coefficients and diffusivities. As you note, in Chilton Colburn there is, but not in a way that typically makes it easy to go from diffusivity to transfer coefficient. Rather the strength in Chilton Colburns analogy is the same as with Reynolds analogy, i.e. that it helps us estimate the transfer coefficient of one entity (e.g. mass) if we have a measurement of the transfer coefficient of something else (e.g. heat)
Actually, I have as a rule never to distribute my powerpoint files. For my students I prepare a "support for note-taking" file/printout such that students need to actively engage while not having to write everything down. There are several reasons for this, one being that what the student does is more important for their learning than what I do and another being that this way I can ask student questions (if/when I give a live lecture) without them having the answer in plain writing in front of them.
Hello, I'm a process engineer and I wanted to brush up my concepts. I came across your videos and they are actually good . Thank you for your efforts.
Thanks Sir. a pregraduated student about to do his titulation exam is very thankful

Hello! Your lecture are easy to understand Sir. Have you prepared a corresponding ppt.
