    Tesla absolutely perfected the use of viscosity with the Tesla Turbine, his own personal favorite invention. Many workshop scientists are working with his idea to perfect and utilize it as the turbine itself can have up to 97% energy efficiency and reach an RPM up to 36,000. I'm assuming the shaft size the rpm measurement was taken was relatively small, but still highly impressive.

    Looking at your videos to do some catching up on the subject matter, but I recently had laser eye surgery (there is a non-sequitur if I ever heard one). I paused the video to attend to something, and when I came back (4:12), I found the text was blurry and I couldn't read it. I thought to myself "Is my vision regressing? Has a cornea slipped, and I'm on my way to being functionally blind again? Did I waste thousands of dollars for no reason? Will I need surgical interventi-" and then my internet stopped shitting the bed, the resolution popped back up to 720 and I stopped having a miniature god damn panic attack.

Spurk, Fluid Mechanics 2020: "it is sometimes incorrectly used as the definition of a Newtonian fluid: there are also non-Newtonian fluids which show a linear relationship between the shear stress and the shear rate in this simple state of stress."

  • @mddelman
    @mddelman 10 หลายเดือนก่อน +2

    Very informative video, thanks. Do you have time to answer a question for me? I have a small vessel filled with water. A thin tube (1.5mm inner diameter) hangs an arbitrary distance below the surface and the top is attached to a valve that allows me to release ink into the water. When the valve is open, ink flows freely. When I close the valve, a vacuum is created at the top of the tube, so the flow of ink stops. However, through what I assume is capillary action, water from the vessel is pulled into the tube, apparently displacing ink, which then leaks into the vessel. This continues until all of the ink in the tube has leaked out. My question is, is there any way to prevent this leakage from happening? I cannot change the viscosity of either the ink or the water. The tube could be modified if that would help, but not to the extent of using a much larger diameter tube.
    I hope you find this question interesting and I'd be most appreciative if you can answer it. Thanks very much!
