There are two main types of fluid flow - laminar flow, in which the fluid flows smoothly in layers, and turbulent flow, which is characterised by chaotic motion and large amounts of mixing. In this video we explore the differences between these two flow regimes. We'll cover how Reynolds number can be used to predict which flow regime will occur for a specific set of flow conditions. And we will look at laminar and turbulent flows in pipes, and how the flow regime affects the pressure drop in a pipe. We'll also investigate why it is so difficult to simulate turbulent flow, and we'll look at some of the different Computational Fluid Dynamics methods which can be used to simulate it.

You do such a great job explaining engineering principles. Especially with your good quality and simple animations. I’m currently learning Fluid Mechanics, and this is easy to understand and interpret. I think you should really start your own online learning program in which you continue to teach these fundamental engineering principles. Like statics, mechanics of materials, structural analysis, fluid mechanics, dynamics, etc. Keep up the good work !
Can't agree more. Very good job indeed.
RIGHT. This subject is difficult. My professor just derives formulas in every lecture and I never know what he's talking about. These videos are so helpful and make the subject 10x more interesting!!
What uni u at?
@@mathew66 Does it have to be a uni tho- I'm not even done w/8th grade and I have to research this U_U
@@anonymousperson2744 ye ur right. Hope u enjoy it and get inspired to become and engineer. Look up Bernoulli’s principle for some interesting stuff.
I'm a CFD engineer and I'm always looking for accessible ways to introduce fluid mechanics and CFD to people. This is a great summary :) Well done.
You have such a class of making other people understand. Actually every Engineering student will agree with me that no Professor can illustrate the topics so easily & a proper way to Understand. Thanks a lot 😍
Thank you, appreciate it!
because he is explaining so little to you in this video.....if he had to teach you that subject in details you may have find him the same as a professor.
these thing are really hard if sufficient amount of it is given.
but undoubtedly that explanation is stunning ❤️
I think its just a matter of content and time. It would have taken him hours to condense all this knowledge in a 15 min video. That's without adding the time taken in animations.
In a real class this would not work unless you want to finish your 1 year course in 5 years.
Plus most professors will take the time to make sure that at least 3/4 th of his class understands the topic. He will sometimes add questions in between the lecture to make students understand the lecture.
And he has to do this for your whole academic year.
So it's wrong to say your professor is worse than the narrator of this video. He is doing his best, with what he has.
nowadays professors are only focused on problem-solving. not a clear understanding of how the equation works, how the theory impact on real-life principles. that's why these types of videos are lifesavers. professors never try to put these types of effort into basic understanding. cuz at the University they only focused on the exam-oriented syllabus. not to disrespect the professors but in reality, if you want to learn more deeply sometimes you have to be disappointed in your professor
Whoever you are....simply stunning!! Really great effort towards establishing this TH-cam channel & I'm pretty sure that your channel going to rock on soon🔥🔥🔥
Definitely he'll be rocking soon.
I've seen some of your videos and I can confidently say that even after graduating from university, I'm still learning much of the basics from your videos. You clearly explain theoretical concepts well without getting too convoluted and technical in the mathematics and equations. Thank you for your hard work.
I won't be surprised if in the future, you would branch out to more specific disciplines such as mechanical, structural, and geotechnical engineering. I will selfishly request that you might do more videos on structural analysis and even possibly nonlinear analysis, haha. But please keep on doing more videos like this. This laminar vs turbulent flow video brings back a lot of memories from my fluid mechanics class even though I will no longer use them because I'm in structural engineering.
This is an amazing video. My son, who graduated from the Colorado School of Mines, tried to explain this to me years ago. I never understood it all that well, but now I finally do. Your diagrams, animations, and explanations are absolutely outstanding for one who seeks to understand. Thank you.
Really appreciate that you’re starting to teach fluid dynamics. I’ve got really helpful methods for understanding solid mechanics in your channel.
Much thanks and keep up the good work :)
Incredible clarity. I never understood this fundamental concept in school 20 years ago. It was just presented to us as plug and chug and move on. Now I'm trying to get the cobwebs out and finally get a PE license and this is very helpful. Thank you so much!
This is brilliant! It's the ability of a genius to explain complex concepts with such simplicity
This is one of the Greatest step towards Education!
I must thank the person who is making such videos, Students across the globe who can't afford to get such awesome lectures also got the Opportunities to learn and to imagine and to Appy.
1-2 MILLION students are goint to follow this channel within a span of 2-3 years! But this channel must be promoted!!! 🙏❤❤
I love how your channel is like 99% of what I'm doing right now! Thanks for the extremely high quality videos man!
This is AMAZING!!! Been here since 10k and I absolutely love your work, your beautiful animations and well-paced explanations really help to simplify the most abstract of concepts, seriously dude imma have to give you a part of my degree at this rate. Thank you so much for putting this stuff out there, and congrats on the sponsor, reward well deserved! Can't wait to see what else you have lined up!
Haha love this comment, thanks! 😄
The clarity and esthetic of your videos are impressive. Thank you for putting work into this and sharing with us :)
Another amazing video with such a good way of explanation! Great to see your branching into other fields than Structural Mechanics. Can't wait to see what other Fluid Mechanics topics you do videos on!
it's always great to review the concepts from diferent peoples explanations, never considered to view the relation to viscosity as the dampening of the chaotic motions of particles. great video already
Remarkable as always!! Such good content, hope you can keep it up with that amazing work. I really enjoy your videos and share them with all my friends who are in the same field. Don't give up and please keep this great content going!
I'm speechless! Incredible video, and explanation! Not sure why there are 2 dislikes, but I'm sensing they are jealouse of your work. Keep it up!
I watch your videos to understand things that I thought I already knew. Your langauge is pretty understandable even though I am not native speaker. Keep it up Sir, greetings from Turkey.
I love how he stated: "traditional engineering tend to be very math-heavy". This has been a HUGE problem for a lot of people including myself with the upper level engineering courses. Luckily we all made it through and have less than a year of college left to get through. Point im trying to make is this: Way too much of our engineering education is about mathematical modeling, equation solving, and calculating some parameter given other known parameters. This is all fine too learn but what is heavily, and I mean HEAVILY skipped most often is the actual physical science of why something is happening according to our observations of the physical world. Engineers come out of school and cant design anything hardly because they very little intuition of how the science actually works and most importantly why it works. Its not all about algebra, calculus, and matlab/python mathematics and coding. Colleges focus on this because its their way of 1, weeding people out of engineering, and 2, its one of the best way to create testing/quizzing for the class. Throughout my whole time in college I can probably count on just my hands and toes how often a conceptual question about how or why a physical phenomenon was even happening. Its alway math math math math, MATH!
I have studied these concepts while i was doing a semester in the US, but ended forgetting about it as I wasn't using it in daily life.
Your video was brillant, as I've been able to remind myself easily all that I had learnt years ago with no effort what so ever.
So good job :-)
Learnt this in my Fluid Mech lecture today and this makes it more clear. Thank you
Wish these videos were available when I was getting my undergraduate degree in engineering 24yrs ago. They are great!!
The best summary on laminar and turbulent flow, including CFD techniques.
I sincerely want to thank you for how great you elaborate these concepts.
You guys are the best, I passed Fluid Mechanics on my bachelor program almost 10 years ago and I almost remembered everything by spending 15 min watching this!! Stunning!!1
The animations of the laminar and turbulent flow were amazing, your work is stunning, as a teacher and as an engineer I give you have my utmost respect and admiration. keep up the good work
Great video.Waiting for more fluid mechanics videos....
This is such a detailed and educational video, thank you very much as this will be beneficial in further understanding CFD.
Please keep making these videos, they're so useful and to the point. Good work buddy!
You finnaly started to grow quickly. Im happy for you, you really deserve it! ❤️
Yes!!! Been waiting for the next video for a while! Fluid Dynamics! Very Excited!!
These videos turn a bunch of hard to digest grass into easily digestible cereal. Thank you so much for making them!!
Superb animations paired with straightforward explanations. Bravo!
These are the best explanations of fluid mechanics I have seen.
Such a well put together and explained video. Great work, thank you. Subscribed
You are doing a great service to the humanity by making things easy to understand as college education is simply interested in completion of the syllabus by going through the chapters as fast as they can without caring whether students have understood or not .
This channel is a gem..!!
Gonna tell my entire class
Excellent video and explanation of fluid regimes
I always thought I understood Laminar flow and turbulent well enough until I watched this video which broadened my understanding. Thank you so much for this! Its brilliant and can we please have more
Love your video❤❤❤. Specially the colors and quality. Explanation is 👍👍👍. Thank you!
I cannot simply imaging a better way to explain the topics you do
Your videos are one of the best ones in describing and explaining concepts!!
I'd request you to kindly post a video on rotational transformation of vectors..
Your content is very clear and puts keys elements of a concept is simple words. Keep up the good work.
you gave me a better revision and understanding of my fluid courses at university 6 years ago ..
THANK YOU !
Every word you say has deeper technical meaning......
Amazing
I wish every teacher would teach as you do. Amazing content.
I'm seeing this channel and it's quality of contents growing exponentially!
Thank you for making the videos, it really helps a lot
This video is a billion times more clear and coherent than my University's lecturer! 😅
I find the clarity and level of detail in your videos is excellent and this one is no exception. Note at 6.53 the Colebrook Equation can be solved for the friction factor f by using Lambert's W-function.
Impressive. You have made these so easy to understand. Thanks for the work !
Everyone will just say after watching your videos that they have learnt what their parrot teacher couldn't teach. Keep the good work bro!!
If you really understood this video that means you have good understandings of fluid mechanics. I think that was taught you by your teacher. It may be true that he was not as much intelligent as you were expecting, still he made you a capable person to understand this video. I am not saying that he is good instead I am saying that he is your teacher.
@@shyamsays I wish he would have in my graduation days. I could get the basic essence of it when I did my Master's program. Thank you for your eye opening comment! Keep commenting keep the good work
One of the best site for learning. Thanks. Keep working .
A small request... Please bring such videos more often... These are tremendously useful and informative... And provides us appropriate pictorial representation... 😊😊
Thank you so much..
Ive never subscribed to any channel this fast ✨ thanks for helping us 😊
Absolutely amazing! You're great man! Thank you for choosing to invest your time in making such invaluable videos! You are making the world a better place for sure!
The most clear explanation ever!
Im studying for my PE and this is super helpful to revisit old concepts.
This is best stuff, I have ever seen on turbulent flow. Thank you sir.
Dang this is a good video. I've watched so many bad or lackluster videos about fluid dynamics and especially turbulence on TH-cam. This one is just great, very well layed out and structured, and everything is correct (ly explained).
Just found this channel and its perfect for brushing skills. Subscribed! keep up the great work man... 👍🏼
Sir Please continue these awesome series.
These are quite helpful.
One can learn much more from these videos than from lectures in universities and colleges wherein mostly theoretical concepts are discussed.
This video is a piece of art. keep up the excellent work!
Your videos are so perfect to help engineering students see what they're learning; something a textbook cannot do. Thank you!
Simply beautiful and simple explanation, thank you
This was a great video with excellent visual models. Thank you.
What a great video that explains one of the key concepts in fluid mechanics lecture! Thanks man👍
Thank you for explaining good topics in simple manner
It's humble request to u sir pls keep posting such videos, it will help a lot for economical backward students 🙏🙏
I reallly adore the way you explain things .. Thanks a lot
I wish my professors explained to me these topics as well as others, the same way you do! It would be so much easier to understand basic principles
Great work sir! You explain things very beautifully...
Just discovered this channel. Super quality content! Thanks
The concepts are very clear. ❤
Beautiful vedio..... difficult topic but lucid explanation...very good
It has been so long since the last time you uploaded a tutorial dude, we missed u
wow..you did such a great job explaining this!
Excellent presentation, very pleasant music in background!!! HATS OFF 👌🏻
For me as an aerospace engineer I must say this is the best video I have seen so far on laminar and turbulent flow. Great job!
GO and learn physics and you will change your mind mate
Really, well explained, mate!!!
AMAZING ANIMATIONS that really help understand mechanical engineering concepts, many thanks from Texas.
Great video! Glad I found this channel. Keep up the good work man 👍

Excellent explanation! Thanks.
it's good to see you are also sharing fluid videos
No one can teach this easily to complex topics.. Great videos..
Huge respect for this kind of dedication, please reply.
Really good video , it explained me more concept that my professor could ever could in a single sem.
That’s brilliant, is easy to understand. Thanks
Thank you so much! Very good presentation and explanation XD
Please Keep it up there is very few channels like yours which gives high-quality education
Such an amazing chanel..I found this at last ..its an ultimately clear explanation ...Thank you soo much..Love from Sri Lanka ❤
Again, hats off sir for such a great video.
Thanks so much for teaching. God bless you!
this is how i study for my fluid mechanics class this channel is GOATED!!!
Everytime you post a video of civil engineering, my heart skips a beat.
Hey guys
Thank your for taking my comment into consideration. Fluid mechanics is difficult to visualize but you guys are making it too easy. Thank you for this.
