    Non-Newtonian fluid ratholing

    https://students.aiu.edu/submissions/profiles/resources/onlineBook/z5y2E6_Perry-s_Chemical_Engineers-_Handbook.pdf#page=634.53&gsr=0 Attempting to read the whole of chapter 6. It may take me a while.

    Non-Newtonian fluid ratholing

    You'd be surprised what our legal department deems sensitive. Pipe size + velocity = feed rate Its difficult trying to vet vendors when you cant tell them anything about what you need without an NDA. I'm envisioning a pipe with scale as a good visual aid. Imagine the scale as a stagnant layer...

    Non-Newtonian fluid ratholing

    Thanks for the reply. My previous job was on a chicken farm. ratholing, bridging, and channeling were common with feed systems there. I think you are right that the term was meant to be analogous when presented to us. Does this mean that the material is a Bingham plastic, rather than...

    Non-Newtonian fluid ratholing

    I am just trying to wrap my head around the pseudoplastic fluid dynamics. We are seeing things that we don't really know how to explain at the moment, like flowing through the pipeline without losses through an open vent [in vertical piping], which triggered my question about ratholing. I am...

    Non-Newtonian fluid ratholing

    I've seen your comments a lot. I was hoping you would reply. You've reference some Chemical Engineering Magazine articles from '68. I can't find anywhere to view or purchase these. I've ordered Darby's text (second edition) as some have suggested. Hopefully that is insightful. My background is...

    Non-Newtonian fluid ratholing

    Hello, Long time listener, first time caller. I have been diving into the behavior of non-Newtonian (shear thinning, specifically) and believe that I am experiencing rat-holing in a Pseudoplastic flow. My question is this: Provided this is a correct assumption, is there a way to determine...
