finally exactly the expalantions I have been looking for. If you come from a different major other than physics like myself from medicine, dont want to deal with derivations of bernaullis equation and all the vectors (awfully painful but tons of respect for those who mastered it) , This is the right series. Simple, concise and sufficient.
Beautiful list, I enjoyed it immensely. And as usual you can't be a studnet without giving your teacher a headache. Can you make a list about the movement of particles in fluids horizontally, as in with river current instead of sinking in the fluid?
Hello and thank you for the video! Quick question: why did you use water viscosity = 1.002? If I understand correctly, this is in terms of cP which is not an SI unit. If all of your other terms are in the SI system, shouldn't viscosity be 0.001002 Pa*s?
+Yasir HHH As time permits. Between my 3 jobs and all the other topics I am covering it has been difficult to finish some of these playlists, but I am planning on continuing.....
May you finish the playlist pleaseeeeee. If your too busy then can you recommend books or links that can teach either the remaining course or the whole thing. thank you. You are one of the best teachers I've ever met in the internet.
Hi and thank you. We are working hard to complete many playlists that still need to be completed. There is just the 2 of us and we still have our regular jobs. We will get there eventually, but we can't promise when. There are not many if any good sources that explain this well, which is why we started making these videos.
ok, surprised however, the cross section is considered when the fluid passes TROUGH the sphere, the volumetric flow, in this case, being expressed as qv=velocity*cross-section, but here fluid is flowing AROUND the sphere, so that was my point, but maybe the correlation has been related to the cross section also in this case. Thx,
Think of it this way. If you are running holding an object, the resistance of the air will depend on how large that object's cross section is (not its volume). There will be a coefficient however that is related to the shape of the object and the flow of fluid around the object.
Thx, Sir...I've have others questions, the Cd depending on the Reynolds Number for example, but it's very late here in France, I'll come back to you soon..Appreciate the discussion.
For that you have to set up the differential equation. The solution of the equation will have a transient component and a steady state component. The transient component will tell you the time it takes to reach steady state. I will be making more videos in the DE playlist on that topic in the future.
Hi sir, could u help me to check what topic u will cover in remaining 8videos? I'm self studying physics as a degree for upskilling as an engineering student. Thank you. Sorry for the trouble.

debendra gurung Glad they are helpful

Maybe in the future. We are currently working on a lot of other topics.
sir your lecture are really helpful
Dear sir, you use for mu of water 1.002 in stead of 0.001002. Is that correct?
Hello and thank you for the video!

Please Mister Michel finish the fluid dynamics playlist
Can you do a video that derives terminal velocity of an annular flow, flowing downwards in a vertical pipe (dropper)?
We love you sir...
excellent
I enjoy physics and truly understand it by your videos the explanation is so completed and perfect thanks
Thank you. You're very welcome!
Great Playlist! Really helpful. Are you going to finish this series anytime soon?

sir fluid dynamics lecture 18 is missing

From previous lecture,stokes' law,Fμ+BF=mg，in this case we have Fμ+FD+BF=mg.
So what are the prerequisites for us to use two different formulas?
Did you ever figure this out? Haha I want to know as well
Thank you .what will be the final velocity if the fluid is in motion? can we add terminal velocity and fluid velocity?
As long as the flow is laminar.
Sir, will you be finishing this playlist any time soon? Great effort as always!
Probably not soon as we are currently working on a number of other topics.
i know it is 1.002 or 0.001002 if viscosity is 0.001002 it must be low amount of viscous force even you can ignore it sir 1.002 or 0.001002 which one?
Why do you use pi*r2 (cross section) instead of the total area of the sphere surrounded by water which is 4*pi*r2?
Since the sphere is traveling through the fluid, we only care about the cross section.
ok, surprised however, the cross section is considered when the fluid passes TROUGH the sphere, the volumetric flow, in this case, being expressed as qv=velocity*cross-section, but here fluid is flowing AROUND the sphere, so that was my point, but maybe the correlation has been related to the cross section also in this case.

How do you determine the time it takes to arrive at a velocity
For that you have to set up the differential equation. The solution of the equation will have a transient component and a steady state component. The transient component will tell you the time it takes to reach steady state. I will be making more videos in the DE playlist on that topic in the future.
Hi sir, could u help me to check what topic u will cover in remaining 8videos? I'm self studying physics as a degree for upskilling as an engineering student.
Thank you. Sorry for the trouble.
We have plans of covering many more topics in fluid dynamics in the future, but at this time we are working on other videos.
Hi sir..I have a doubt why we use Area,A=πr^2, as it is a sphere it should be 4πr^2 ryt?
For the drag coefficient, you need to use the cross sectional area.
Where are the rest of the courses?

Videos take time, and I do work 3 jobs.
I may have some more time this summer to continue the fluid dynamics videos.
Thank you...
