Graduate Fluids Lesson 11D: Observations: Stokes Flow Over a Sphere
Graduate Fluid Mechanics Lesson Series - Lesson 11D: Observations: Stokes Flow Over a Sphere
In this 11.5-minute video, Professor John Cimbala discusses several observations about the Stokes flow (creeping flow) equations, including fore-aft symmetry (or antisymmetry) of the streamlines and velocity and pressure fields. He also compares potential flow and creeping flow over a sphere.
A complete list of the videos, the annotated notes for each video, and the Equation Sheet can be found in this Excel file:

ua-cam.com/play/PLQR3QcO-W5hc32zBQiI14HzqEb_y6pIh6.html
These video lessons are intended for use by first-year graduate students taking their first graduate-level course in fluid mechanics. For example, at Penn State our first-semester course is called Foundations of Fluid Mechanics I (ME 521). A second course follows in sequence, typically in the second semester, called Foundations of Fluid Mechanics II. Both of these courses were created by Professor Cimbala. The video lessons and notes closely follow the notes that Professor Cimbala uses when he teaches the course. Except for a few potential notation issues, however, these video lessons may be useful as a free resource at other schools and for anyone wishing to learn about fluid mechanics.

Thank you for your videos. Your videos on fluid mechanics are helping me a lot in my engineering. Love from Bangladesh.
Professor Cimbala, congrats again on such a high quality content! I’m currently studying a master’s in energy engineering and next semester I must take aerodynamics and turbomachinery. I have no background in mechanical engineering (I am an electrical engineer). Do you think that this video series will help me fill in those gaps and make both courses less of a challenge? I greatly appreciate any feedback from you. Merry Christmas and a happy and healthy 2025! Let the fun (fluid mechanics) begin! 🎉
Yes, my video series should certainly help you learn the basics of fluid mechanics. That's why I created them! Thank you for your comment. Please tell your friends and colleagues about my UA-cam channel where there are over 500 free videos about the Bible, fluid mechanics, science, math, Excel, statistics, air pollution, and other topics. I would greatly appreciate it.

didn't quite get the easy part of calculating pi3, last part. someone explain?
PI 3 is simple because it is just a length over a length. All the other repeating variables drop out. You are welcome to go through the step by step procedure to calculate this PI and you get the exponents I mention in the video for PI 3, which turns out to be epsilon divided by D.

@johncimbala sure sir
Hi Professor, this may be because the fluid dynamics class that I'm taking is specific for environmental flows... but we account for baroclinic production of vorticity as well in the vorticity equation. Is there a specific reason why the vorticity equation you derived doesn't include baroclinic production? Thank you!!
Well, there is only so much material we can discuss. In Mechanical Engineering, we typically don't encounter baroclinic situations. Thank you for your comment.

F bucket on wheel should be positive to conform to the sign convention used throughout and in this example as well. Right?
The signs are correct. The force of the bucket on the wheel is opposite in sign of the force of the wheel on the bucket. And you need to think in terms of the control volume, not what you think physically, since you can treat the control volume as a "black box" meaning that you can solve the problem without even knowing what is inside.

GOD PLANTED BOTH THE MALE GERM AND FEMALE EGG. OTHERWISE HE WOUD HAVE BEEN A DEMIGOD LIKE HERCULES, ACHILLES, PERCUES ETC. SUPPOSEDLY ZEUS CAME DOWN IN A SHOWER OF GOLD DUST AND LAY WITH HUMAN WOMEN. NOT GOD! THE HUMAN BLOOD AND DNA WAS CORRUPTED IN THE GARDEN OF EDEN WHEN THE WALKING TALKING INTELLIGENT MAN SERPANT SEDUCED EVE. THAT IS EXACTLY WHY JESUS HAD TO BE COMPLETELY OUTSIDE HUMAN BLOODLINES. HE WAS ALL GOD IN FLESH FORM.
My bible says in King James Bible The prophets described this era with the expression, “the lion and the lamb shall lay down together…” But there is a slight, ever so slight, problem with this: the expression, the lion and lamb shall lay down together does not occur in the Bible! The closest we can get to it Isaiah 11:6.

My view Adam was fully human, yet he didn't he didn't need male and female chromosomes. And him about being son of David, i don't think it has to be literal since his genealogy from Joseph isn't literal either. The problem i have with option 4 is, did he go back to heaven with a body therefore changing?
All human beings have the same number of chromosomes (except for Down Syndrome), so I don't follow your line of reasoning about Adam. I obviously take a more literal view of the Bible than you do. Finally, Jesus did go back to heaven but with a resurrected body that was changed from his old body yet still recognizable (still had the scars, for example). We who believe will also receive new bodies that are like that of Jesus. Thank you for watching my video and for your comment.

After Jesus was born Jesus He had siblings eg James who was called half brother of Jesus....anyway there is enough evidence for one to have salvation there is no need to digg down in the extra books we need read the 66 books in all which The Holy spirit has inspired..That is Genesis to revelation..And Jesus will Judges all of us.. don't forget He will be The Lion and not The Lamb .
Thank you for your comment. I actually have another short video about Jesus' brothers. ua-cam.com/video/R5lgepB6sWc/v-deo.html I note here that having these "half brothers" does not negate the conclusions from my DNA video.

@@johncimbala well after a long haul i think i got a solution for that. But its only for the mac laptop. Export your ppt to mp4 with Hevc transparency compression. It says that the background of a video can be removed by that process. Not sure if that worked since i use windows
@@jyotindrak47 Most video software allows you to remove a background. I use Camtasia for my videos and it is easy to remove a background. That is how my characters appear with a transparent background on my videos.
@@johncimbala great. Lemme try that one. I have subscribed your channel

GREAT VIDEO AND AWESOME CHANNEL. I'M A HUGE FAN. I JUST HAVE ONE QUESTION ABOUT THE HYDRODYNAMIC BOUNDARY LAYER. WHAT ARE THE BOUNDARY CONDITIONS?
Generally in a boundary layer, there is the no-slip condition at the wall and then the boundary layer asymptotes to some outer flow speed at the "edge" of the boundary layer.

What would the total head loss in the system be (in the context of sizing a pump for application). Would the total head loss be the head loss through the branch with the greatest losses? That way if the pressure at the junction is high enough to overcome the losses through the worst-case branch, then it can also overcome the losses for the other branch?
It would be the same pump requirement regardless of whether you consider one branch or the other branch or just the junction point. The pump would not know the difference.
Hello, sir. So, the given is Tee and the inlet volumetric flowrate is Q1= 100 GPM. The oulet volumetric flowrate is required. The inlet diameter d1=d2=80 mm (one of the outlet) and the other one is 40 mm. How do you solve the 2 outlet volumetric flowrate if the only given is Q1 and the diameters, coz there will be 2 unknown.
As I explain, you solve the two parallel sections independently, pretending that only blue fluid goes through one pipe branch and only red fluid through the other. The key is that the pressure at the tee is the same regardless of which branch you are considering. Thank you for your comment.

John the Baptist is excellently depicted by Harry Hagrid!
Thanks! I think he will be a popular character.
If Prof. Skeptic would buy a car from Luke, I would as well!
So would I. I already bought three cars from Luke!
Because of you I loved learning fluid mechanics. Thank You

Hilarious!!
Professor, I have one problem that I have been stuck for some weeks...maybe you can give me a hand... It is a problem where the fluid hits a sumerged constant area that is inclined. The issue here is that this sumerged piece doesn´t have rectangular shape, it is triangular. In conclussion, it is a triangular gate which gets hits with a fluid in one of its sides. Can you clear me the path a little, thank you in advance!
The answer is right in the same video you commented about (Lesson 03B). I show several shapes, one of which is actually a triangle.
Well done, keep it up, great job.
Eventually, after a long, difficult, 3 day weekend, he left us. How much better it would have been had he stayed
Actually, if Jesus had not left us, i.e., if he had not died on the cross for our sins, it would NOT have been better for us. Jesus' death provided a way of salvation for us! His resurrection proved that he was indeed who he claimed to be. Thank you for your comment.

@@johncimbala I'll do my best to sin as much as possible to make sure he didn't die for nothing.
@@grandpavan8335 That is really sad. I am sorry for you.
@@johncimbala Don't be sorry for me. I prefer reason and what's TRUE over myth. I used to be a Catholic, but nobody answered my questions with anything better than "don't ask questions."
@@grandpavan8335 That is too bad. I encourage questions! I too struggled for many years not believing in God, and did a lot of searching and reading until I learned the truth and rejected the myth, as you say. God is real and I pray that you come to know him.
Is this topic also called “scaling?”
I have not heard it called that. I always learned it and taught it as "similarity solutions" Thank you for your comment.

@ I think I have found a video of yours that addresses dimensional analysis. Thank you again for the great videos.
@johncimbala, Professor, I wonder if you are willing to make a quick video demonstrating how to program the iteration method used in this video in MATLAB? I assume there is a while loop, but I am struggling to get the code right: clear clc g = 9.807; H = 35; L = 20; D = 0.025; rho = 998; epsilon = 0.00010; mu = 0.001002; Ksum = 13.35; f = 0.04; % Guess f n = 1; while f(n+1)-f(n) > 0.00000001 V = sqrt(2*g*H/(f*L/D+Ksum)); % Calculate V in m/s Re = rho*V*D/mu; % Calculate Reynolds number % Solve Churchill equation for new f A = (-2.457*log((7/Re)^0.9+0.27*epsilon/D))^16; B = (37530/Re)^16; f = 8*((8/Re)^12+(A+B)^-1.5)^(1/12); end f = sprintf('%0.4g',f)
I am not that great with MATLAB. Perhaps someone else can give you some hints on your code. Some of my students use the Solve function in MATLAB effectively. I usually use Excel for this kind of problem. Thank you for your comment.

In the iterrations example (2nd example), why is the minor loss coefficient of the oulet 1.05? How did you assume that the flow is turbulent without knowing Reynolds number initially?
Ahhh... good question. You don't know beforehand. So, you must choose laminar or turbulent and then go through the analysis. At the end, calculate Re and see if your assumption was correct or not. I did exactly that in Lessons 08D and 08E with a different example. I assumed laminar but found out that it was turbulent. Then I repeated the problem as turbulent. Thank you for your comment.

I think not. And please do not call me Father. I am not a priest or anything - just a professor.
@ ok mr professor thanks
@@johncimbala by the way professor i like your videos so much especially fluid mechanic videos💙. and the thing i said above I just wanted to make a joke but I sorry you didn’t get it 😢. My apologies
