    This series cements the fundamentals in a way I could now fully explain the processes to my family. That is ultimately the level of understanding we all strive for! Thanks again.

      Hi@@tutstorial8474,
      I’ve already got a few videos up on losses in pipes, hope they are useful:

      Yeah these are type of explanation every students wanted in campus. I wonder how he can explain it with such clear insight. He must have read some special book.

    The viscus force is cohesion quantified .
    Laminar flow is Cohesion in action caused by adhesion .
    Turbulent flow is adhesion in action caused by cohesion
    In the prior the cohesion is the dominant force
    in the latter it is dominated

    Its really very simple , when adhesion over come cohesion the molecules of water loose that uniformity . The energy of the flow causes the molecules to follow erratic paths . Helium will not do this hens its super fluid properties .

    Turbulence, the greatest unresolved puzzle in Physics. Einstein described the problem as intractable. He gave up trying to solve it. But it's ubiquitous in the universe.

    Reynold's number also has density in the numerator, unless you were talking specifically about water and S.G.=1. Otherwise great material!

    • @fluidsexplained1901
      @fluidsexplained1901  2 ปีที่แล้ว +1

      Thanks for the comment. I am using the version of Reynolds Number with Kinematic Viscosity, where Kinematic Viscosity = Absolute viscosity over Density, so the Density is there in my working, just hidden. This definition of Reynolds Number is exactly the same as (Density x diameter x velocity) over (Absolute viscosity). I find this version quicker to use, but it does sometimes cause confusion as the other version is probably more common. Hopefully that makes sense?

    You should get familiar with the difference between damp and dampen.

    Make this experiment with very fine particle inkjet printer or in fair of science find dye that is exactly in size or water molecule and is not transparent, yes such particle don't exist but that is point of scientist Brownian motion 10^14 hz collisions observed pollen particles of flowers jiggles 1000 smaller paint (dye) particles of potassium permanganate jiggles faster mixing of layers is much faster, no stratification of layers of laminar flow exist.
    1:40 Your camera showing only 1/3 length of total pipe but even here you see that already intensity of dye are mixing, no even flow layers stratification. Not forget fact that water molecules compare to dye particles are 10000 times smaller, inject printer dye have smallest particle compare to water 1000 times bigger than individual water molecule. Take very long pipe and use see than no laminar flow exist. What you can see that Brownian mixing follows sinusoidal pattern Kármán vortex street. Of course which is behaviors of Brownian motion of mixing not flow regime of laminar or turbulent.
    Reject Brownian motion of molecules is rejecting all atomist model of matter, according to Reynolds flow is perfect layers of continuous flow that sometimes moves in vortices and eddies if flow is high (turbulent). And we stuck with this interpretation to this day.
