In this video we take a look at viscosity, a key property in fluid mechanics that describes how easily a fluid will flow. But there's more too it than that!
We'll start by defining viscosity using Newton's Law of Viscosity, that describes the linear relationship between the shear stress in the fluid and the strain rate, and how it relates to the dynamic and kinematic viscosities.
We'll also explore how viscosity is dependent on temperature - the viscosity of liquids reduces with increasing temperature, but for gases temperature has the opposite effect. We can explain this by looking at what causes viscosity on the molecular level.
Another interesting aspect of viscosity that's covered in the video is non-Newtonian fluids, like shear thinning or shear thickening fluids, for which the relationship between the shear stress and the strain rate is non-linear.

Just perfect timing as i have fluid dynamics this semester!
Amazing... me to
Me too ahahah, i have aerodynamics
i was literally learning viscosity in my course earlier today... weird (but very helpful!)
Me too hahah I have fluid mechanics this semester
Wish u luck lol
I did it in january in Italy and that exam was tough af
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.
Honest to god, I think without your videos I would never properly understand the things I learned at uni. Very concise and explanatory!
+1 :D
*God
Can't imagine the hard work behind these videos. The script, animation, and editing are so perfect.
This 12:54 minutes video covers half of my fluid dynamics course. Great explanation and conceptual understanding.
brother you are just kill'n it with the explanations and animation
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.

I've studied this and passed the class with an A+, and I've just understood viscosity today
True story
Me too
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?
@@General12th I had a limited knowledge of viscosity I knew how to solve problems but I didn't fully understand Viscosity
Goes to show teachers gives A+ to the wrong students.
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.
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.
I like how DETAILED your explanation is !!! JUST KEEP POSTING VIDEOS PLEASE !!
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
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!
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!
I had a lecture about viscosity at fluid mechanics today, and this was a huge help, thanks a bunch!
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.
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.
Perfect timing since we just started our viscosity lectures this week
One of the best explanation in fluid dynamic I have ever seen, thank you very much
by far, this is the best explanation of viscosity I've ever come across. Thank you!
This channel is about to revive my grade in my aerodynamics class
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.
I learned the entire first three weeks of fluids from this single video. You’re the goat
All your videos are always been great. I love the animation. Thank you for uploading again.
I really loved your presentation and demonstration of the concepts, glad that I know this channel.
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!
Excellent explanation! I wish engineering professors could have the time to make videos like this for their classes!
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
I never intended to miss any of your videos
Good presentation. Crystal clear
This video has clarified so many concepts which i was struggling to grasp. Thank you!
Thank you for your clear explanation and great animation ❤️
this is the best video of my life about viscocity.thanks so much for hard work behind this master piece
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❤🙏🙏
Awesome video. Understanding these topics was never this easy !!
This is just brilliant! Very well explained
I can't explain how much helpful is this!!!
Thanks.
I want a lesson of thin vessel and hoop stress acting on it.
This channel is just soooo BEAUTIFUL
Great Video! We want more.
this is the most educating video on fluid dynamics on youtube :) perfect...
Thanks for the effort you put into it. THANK YOU!
Very beautifully explained.
Extremely helpful. This was great. Thanks a bunch!!!
This video was very useful!! I'm so grateful for your lesson about viscosity :)
Great video. Perfect explanation with visual.
Wow! I wish I had more lecturers like you in varsity. So good!
I'm lucky, at least now, to learn these concepts from this awesome channel!
Already an MSME/Aero but would have loved this! Perfect explanation!
Excellent video! Thank you
Excellent video, great explanation! Thank you!!
Excellently explained
Excellent material. Really teaching art.
You get things understand very easily.
Thankyou for your efforts 😊.
Thanks for the effort! The animations are great!
this video is pure gold
Excellent timing for my fluid dynamics class I'll be taking when I go back to college in a few years!
Best video on viscosity of fluids out there! 💯
This video gives clear idea about topics.thank you
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.
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!
Thank you so much for explanation .
These are incredible. Thank you!
Another amazing video! Thank you!
The animation is simply beautiful! That itself illustrates 70% of the concept behind this topic.
Thank you soo much for your excellent videos!
Please accelerate your activities!!!!
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 UA-cam channels such as yours to help them out.
Great explanation of velocity differences in the pipe.
Great job. Thank you very much!
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.
ALways Love your content!
Thanks man! Beautiful video
Great video, as always, keep it up!
thsi channel is just gold
