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: ua-cam.com/video/6h1ZylIAyN8/v-deo.html ua-cam.com/video/zZ1yaJerGD0/v-deo.html ua-cam.com/video/YyR5IMj89Iw/v-deo.html
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 . Laminar flow is cohesion in action caused by adhesion . Turbulent flow is adhesion in action caused by cohesion
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.
"When I meet God, I am going to ask him two questions: Why relativity? And why turbulence? I really believe he will have an answer for the first." Werner Heisenberg.
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.
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?

Thanks so much for the encouraging comment!
You're amazing... Most underrated channel😮💨
Thanks so much for the comment!
this channel is so underrated
Thanks for the encouraging comment!
Do a video on losses in pipes please🥺
Hi@@tutstorial8474,

oh I'm gonna check it, tnx 😁
@Fluids explained..Plz...not given any link such this way.Bcz,your channel may be suspended anytime.So be careful.
i love your fluid mech videos, super clean explanations. i hope you could make more videos on losses in pipes!
Many thanks for the encouraging comment, very glad you enjoy them!

great video!!! great explanation. Amazing shots! Thank you!
Thanks for the comment!
thank you this was very helpful
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
Hi, I was wondering what the tubing you used for the dye injection was called and where you got the dye flow controller from?
thanks for your effort mate.
Thanks for the comment, glad it's appreciated!!
Masha-Allaah..good explanation!
Thanks for the comment!
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 .
Laminar flow is cohesion in action caused by adhesion .
Turbulent flow is adhesion in action caused by cohesion
i want to simulate this kind of fluidflow but how😥

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

@@fluidsexplained1901 it does now, thanks!
You should get familiar with the difference between damp and dampen.
Thanks for the feedback. There is always room for improvement but hopefully the science was ok :)
