Let's all take a moment to thank you, your videos are really really precious for engineers like me, and even more for engineering students and all those who are curious about engineering. So Thank You.

[@centaureacyanus7026]

Honest to god, I think without your videos I would never properly understand the things I learned at uni. Very concise and explanatory!

[@akshatverma3529]

+1 :D

[@TVjoakim]

Just perfect timing as i have fluid dynamics this semester!

[@henrynwosu6277]

Amazing... me to

[@gian2kk]

Me too ahahah, i have aerodynamics

[@euanocurry2144]

i was literally learning viscosity in my course earlier today... weird (but very helpful!)

[@nahuelp1932]

Me too hahah I have fluid mechanics this semester

[@marcomaselli8986]

Wish u luck lol I did it in january in Italy and that exam was tough af

[@rajvardhanshinde6251]

Can't imagine the hard work behind these videos. The script, animation, and editing are so perfect.

[@VJ-dv4ub]

brother you are just kill'n it with the explanations and animation

[@darshangohel6873]

your all videos are just masterpieces. I just can not imagine the amount of time and effort you put into it. please continue this amazing series in fluid mechanics and aerodynamics.

[@sofiansaleh]

I've studied this and passed the class with an A+, and I've just understood viscosity today

[@ksefonimenos]

True story

[@thalescarl1589]

Me too

[@General12th]

How did you get an A+ without a good understanding of the underlying mechanics? Are you just good at identifying which equation needs to be used to solve the problem at hand?

[@sofiansaleh]

@@General12th I had a limited knowledge of viscosity I knew how to solve problems but I didn't fully understand Viscosity

[@ShaneshaS]

Goes to show teachers gives A+ to the wrong students.

[@ManiKumar-ig3ee]

Really outstanding. I am also a faculty of fluid mechanics. Your efforts and money spent in making extraordinary animations, Really deserve appreciation . I salute you dear.

[@spykey312]

Dude, this channel is a lifesaver! I have a presentation on this in 2 days and was literally looking for this exact kind of video just last night. All of a sudden, this pops up in my recommended! Phenomenal stuff! Much appreciated!

[@User_alphagammabeta]

This 12:54 minutes video covers half of my fluid dynamics course. Great explanation and conceptual understanding.

[@peterpan0201]

Thanks!

[@mibrahim4245]

I like how DETAILED your explanation is !!! JUST KEEP POSTING VIDEOS PLEASE !!

[@edukamp1]

I find it amazing how simple and resourceful your videos are, of course they scrape the top of the content, but as an engineer graduate and a generalist, your videos tickle my brain to go after it and never lose this knowledge. Thanks a lot, please never stop producing and posting! I miss the engineering classes in my life.

[@Goose____]

this channel is single handedly saving 80% of my grades

[@גיאדרי]

As a person who works with non newtonial and thixotropic fluids on daily basis, a video on them will be a great follow up. Great, intuitive video as always

[@benhelm6212]

This channel is about to revive my grade in my aerodynamics class

[@mm42rn42]

I learned the entire first three weeks of fluids from this single video. You’re the goat

[@elsteppenwolf]

Excellent explanation! I wish engineering professors could have the time to make videos like this for their classes!

[@Michallote]

What they mainly lack is skill my friend. Those animations are very professional (yes also time consuming) but even if they had the time to make them, they would probably be at best a well planned power point presentation. This man's work is insanely good

[@JesusMartinez-zu3xl]

I just started my fluid mechanics class and im so happy you have a video on this subject!! Now i have a deeper understanding of viscosity.

[@ItsJustparsa]

I had a lecture about viscosity at fluid mechanics today, and this was a huge help, thanks a bunch!

[@troybaxter]

I'm kicking myself right now. Why didn't I watch this video 2 months ago when I was just getting started on my flowmeter project for work. I could have been more accurately calculating the Reynolds Number and the state of the fluid than I already was. Dang!

[@saifullahbashir6317]

I accidentally clicked on this video and and found it amazing.One of the unique and best thing ever watched on internet. Big ,Thank you. Will join this family by the end of this month.

[@ellyvatedaf]

Perfect timing since we just started our viscosity lectures this week

[@McDJpedro]

You nailed it! You made an amazing and easy video to understand a difficult stuff! Please, keep working on this project because you're onee of the best teacher that I've seen in my life! Thank you a lot!

[@lilianahategan7939]

I was thinking that all this knowledge would've been impossible to be developed by a single person therefore I feel lucky so many brilliant people build upon each other's work and today we have all this.

[@abdulmajeedalrajhi6737]

One of the best explanation in fluid dynamic I have ever seen, thank you very much

[@saisrirajnallam]

I never intended to miss any of your videos

[@mr.mustache4743]

This was amazing content; Thank you for explaining this in a concise and efficient manner. I truly appreciate the work you put into producing this excellent explanation for the entire scientific and youtube community.

[@eladnanimohammedamine1271]

Watching you from France where the engeneering studies system is way different and way more based on theory and formulas, it's a blessing to see such goog visual interpretations. That's great work I'll talk people into seeing ur work to have a deeper unstanding of these physical concepts.

[@jelenaradovic8184]

by far, this is the best explanation of viscosity I've ever come across. Thank you!

[@AJMusicUganda]

this is the best video of my life about viscocity.thanks so much for hard work behind this master piece

[@gautam5895]

The animation is simply beautiful! That itself illustrates 70% of the concept behind this topic.

[@xiujiaoqiu8558]

This is one of the best videos that explaining complicated concept to such a easy way

[@adilriahi938]

Great Video! We want more.

[@elifyldrm7736]

this is the most educating video on fluid dynamics on youtube :) perfect...

[@sujathanagalakshimi4561]

Good presentation. Crystal clear

[@kentayagi9530]

I am studying about shear stresses and curious about the formula for shear strain. Uploading a video about viscosity and briefly discussing shear strain makes my day. Your videos are really timely. Great content as always! SUPERB! Keep up the good work! No regrets turning on the notification for the channel!

[@spindash64]

4:10 looking at viscosity this way, it almost seems this behavior is THE defining boundary between solids and fluids: solids are only solid BECAUSE finite force can only cause finite total deformation, and fluids are only fluid BECAUSE finite force can apply a finite velocity

[@ioannistasio703]

As a first year student of Naval Architecture and Marine Engineering at National Technical University of Athens, this was very helpful, keep going man!!!

[@mandlamaseko6785]

Wow! I wish I had more lecturers like you in varsity. So good!

[@ranaatul1306]

thsi channel is just gold

[@jeslela]

Best video on viscosity of fluids out there! 💯

[@JuanNunez-dt1fn]

This channel is just soooo BEAUTIFUL

[@RahulNatha]

I'm lucky, at least now, to learn these concepts from this awesome channel!

[@ingGS]

I don’t need to watch the video, I like it immediately and then watch, I know it is going to be good and I will watch again even.

[@MegaOjetemoreno]

Excellent material. Really teaching art.

[@joshuawood5304]

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.

[@JanLaalaa]

This video has clarified so many concepts which i was struggling to grasp. Thank you!

[@shubhamupman7260]

Wow 🤩top quality videos as always!! Never understood velocity profile, Dynamic viscosity and kinematic viscosity soo well before!! Thank you soo much for this explanation❤🙏🙏

[@jovenagocoy4952]

All your videos are always been great. I love the animation. Thank you for uploading again.

[@darshank2331]

U people are making every one to like engineering awesome ❤️

[@icebluscorpion]

Could you also visualize next time the shearstress of a fluid flowing in a lotus coated tube? Where you have slip condition. Would be interesting to see how the maths pan out for that condition 🤔

[@madamcurienobel]

many thanks for the comprehensive explanation on viscosity!

[@SumitKumar-hh7yz]

Very beautifully explained.

[@oli4627]

Was struggling to understand conceptually what exactly i've been calculating but your videos really helped with that. Top g :)

[@damieng7280]

Thanks, i ve fluid mechanics II exam in 3 days. You saved my life

[@General12th]

Excellent timing for my fluid dynamics class I'll be taking when I go back to college in a few years!

[@EliasOska]

Would have been really cool if you guys were around when I was in engineering school 8 years ago. Thanks for the recap!

[@muh6099]

I really loved your presentation and demonstration of the concepts, glad that I know this channel.

[@Octavius-ig6jt]

@3:23 it is written \gamma = tan(\frac{\Delta u \times \Delta t}{\Delta y}). But isn't this incorrect? Isn't tan(\gamma) = \frac{\Delta u \times \Delta t}{\Delta y}?

[@EngineerHunter]

Great video. Perfect explanation with visual.

[@babajungLA]

Really enjoying this series on Fluid Mechanics. Once this is complete, how about a series on Thermodynamics? 😊 I'm actually very jealous of students going to college now since they have many resources online and great KZbin channels such as yours to help them out.

[@meatmybest3459]

Just beyond appretiation!!!!

[@Slinkyfest2005]

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. Solid video though matey, very informative, thank you.

[@AS-jb4my]

Newton is the greatest mind in history. Whenever I study any enginnering subject his name always pop up, it's like he had 72 hours a day, it's insane but really inspiring at the same time.

[@abienojieokojie2116]

Have you heard of Euler?

[@houtouzou8709]

Or Bernoulli

[@houtouzou8709]

Fun fact: Euler and Bernoulli are not two people but whole families lol

[@AS-jb4my]

@@abienojieokojie2116 of course I did, great scientist but no one comes close to newton in my opinion.

[@ypieieyp4828]

My 14th great-granddad, who fed his family through the harmless craft of coin clipping, might have agreed about Newton's intellectual capacity, but found him to be severely deficient in empathy.

[@FrancoFerrucci]

Hi there! At minute 3:23 it says tan() but I think it should be tan-1(). Cheers!

[@mrslave41]

i agree. aka arctan.

[@friendsanfriends12]

Awesome video. Understanding these topics was never this easy !!

[@JoelRTLCosta]

Thanks for the effort! The animations are great!

[@andresvasquez5411]

It' pronounced "oil-er", not "Youler". In german, the combination "eu" is pronounced "oi"

[@ateium2409]

eu is more specifically a digraph

[@joshuagrumski7459]

I cringed at the pronunciations he had for some of the names. I’m a math dude, and Euler’s da bomb to me

[@rohansrivastava1254]

Right What about “kirchoff”

[@joshuagrumski7459]

@@rohansrivastava1254 you see, I realize that it’s pronounced “Kirch-Hoff,” but I will say I pronounce it “Kirk-off,” but that’s mainly because I had a teacher with that exact last name and he told us all to pronounce it like that… it’s a bad habit now, lol. Euler’s name, though, is the only one I was corrected until I got it right, and now I cringe at mispronunciations

[@sameer26121980]

Yes you are right. Euler is not Euler. Euler is Oiler. 🙄 Funny english

[@SharperthanA]

Already an MSME/Aero but would have loved this! Perfect explanation!

[@Benji.the.Poodle.2024]

Are there any similar KZbin channels with such amazing videos/demonstrations for Chemistry and Physics?

[@mddelman]

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!

this video is pure gold

[@ehsanullah6351]

Efficient work by the efficient engineer ❤

[@David_Lloyd-Jones]

At 1:45 ~ 1:55, you're confused. Slope is rise over run, so you mean small slope near the origin and large slope higher up the curve -- the opposite of what your voice-over says.

[@James-sb6do]

I believe It’s because with respect to y not x. I was thinking the same thing and was trying to find a comment for clarification

[@thephilosophicaluser]

Thats wrt x

[@JamesVestal-dz5qm]

I taught my fellow jardine residents about heat transfer in Minnesota. Kids in Minnesota are taught lessons about frostbite that kids in kansas are not because of differences in climate.

[@zahraakhalife9150]

Thank you for your clear explanation and great animation ❤️

[@MrGold-17]

Very good animations bro, keep it up!

[@grumpystudiesengineering1517]

The statement at 2:30 is wrong. There are fluids that obey Newton's law of viscosity but aren't newtonian fluids. 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."

[@ferdowsalom049]

shouldn,t the graph of the velocity vs y graph be mirror about 45 degree center passing line? I think it should flip🤷‍♂

[@sonukr1807]

Amazing ...Need more on Fluid Mechanics

[@brucelee1255]

Thank you so much for this video , it helped so much I was so confused about this topic

[@cronobactersakazakii5133]

I knew the cornstarch / water mix to create a non newtonian fluid (thickening) I didn’t realize there were other fluids that would have the opposite effect (thinning) such as paint. Anyway, a very efficient 12 mins summary on flyids and viscosity
