Thanks, great explanation!

Great video, sir. Thank you so much. I have a question though.

Hey guys! I'm working in research on a topic called 'organ-on-a-chip' which uses shear stress to mechanically stimulate cells. Currently I'm looking in depth at the physics side of this topic. However, based on this video and the 'no-slip condition' it seems to me like this mechanical stimulation is not achieved since the cells in my system are basically located at the place where the dye is injected to the wall, which stays put and does not experience flow/shear stress. Am I correct? Thanks

What is the textbook that contains this example?

[@matthieulouise8323]

if y= -h, then du/dy should be +ve Sir. Don't you think so ?

[@Nacho1234]

Dear Casey, I think your du/dy is wrong since h should be squared, and so in (tau)xy

why is y=-h
