Hi everyone, I was wondering how to best calculate the breakage resistance of a drill hole which is being flowed through with a certain volumetric throughput within a polycarbonate (PC) rectangular plate. Well basically, the breakage resistance of the PC around the drill hole :) The plate is...

Oh yes, I also made a mistake above leaving out the ##10^{-3}## for the volumetric flow in a blood vessel. I just forgot it when typing up my manual notes. Now it all makes more sense :)

D'oh, that was daft of me. Thanks :) Ok, but then I see no other issue with the calculation...other than intuitively it seems very small to me. But science doesn't care about intuition I suppose :D

After calculating, the ##Q## I am getting seems rather small to me. I based the calculation on the wall shear rate of the carotid artery that is ##γ = 333,3 s^{-1}## ##a = 0.0104 m## and ##b = 0.002 m## So, ##A^2 = 4.3264*10^{-10} m^2## ##λ = 1.253## ##P = 0.0248 m ## (as the entire channel...

Thank you very much! That's a great help!

Yes, its fully developed laminar flow. That far I have managed to calculate :) If possible it would be best for me to know how the shear rate behaves across the cross section, however at the walls would suffice also, as the shear rate for blood that is usually found (edit: in literature) is...

Hi everyone, Non-physics student here, and slightly in over my head :D I am slightly stumped for ideas regarding the calculation of the shear rate in a rectangular type channel, which I need to effectively simulate a blood flow type condition in a channel that has to be rectangular due to the...
