- This physics video tutorial provides a basic introduction into viscosity of fluids. Viscosity is the internal friction within fluids. Honey has a high amount of viscosity compared to water. Honey travels slowly down an inclined plane where as water will flow down quickly. Viscosity can be reduced by increasing the temperature. This video explains how to calculate the coefficient of viscosity and the velocity gradient in a typical example problem. The velocity gradient is the ratio between the velocity and the distance between the moving and stationary plate.

When i got my degree, i want to thank u personally.
me too
Get
You want to serve him food 😂😂😂
Kamusta na kaya to?
Thank you! You explained well throughout the video, clear and concise, now I understand even more!
Thank you so much for your videos. They're super helpful!
Thank you! You're a hero! You changed people's lives. I mean that.
he ACTUALLY changed my life i didnt understand this for days until this video
I have watched a lot of videos regarding this topic yet I couldn't grasp the concept but your 10 minute video is so awesome it made learning very easy thankyou
From inorganic, organic to fluid mechanics fluid subjects. You were there. thank ü, Mr. Organic chemistry.
Thank you for your detailed video. May I have a question? What is the relationship between hydraulic gradient and fluid velocity when considering different viscosity?
is there ANYTHING i needed and u didn't help me in in the past idk like 4 years ?
God bless your mind.
Excellent.Very easy to follow.
This video really cleared up Newton's law of viscosity for me... you guys are great keep doing what you're doing, your reward will be great💪
Thanks for a very clear explanation!
I noticed that a viscous substance like oil acts like or is analogous to matching impedance. If there were no oil, one piece of metal passing over another experiences maximum friction. Bu adding oil, the gradient of friction, converts maximum friction to a much lower friction allowing the passing metal to move more freely. Anyway, it's just an observation. If I am wrong, please let me know.
Another great video. Thank you!
Great video, very helpful, very clear. Thank you.
Very helpful, thank you.
Excellent clarity!!!
Perfect, I hope that I saw this before today's Quiz !!

master of all ,thank u
Can you make a videos on ductile , hard , tough and the properties of solids in general ?
thank you so much.your videos are great🌺
Thank you. I do appreciate this video as it helps me to solve my physics paper question. Thank you so much for making this interesting video. I do learn a lot. I do hope that you will update more video just like this one.
A great video. Thank you sire🩷
Understood immediately 😊❤❤❤
you're such a life saverrrrrr
Which mathematics need to study hydro vortex or hydro spiral motion of fluids ??
Thank you, i understood much better...നന്ദി
You're awesome men! Thank you for your videos, they are very helpful.
Nice explanation
i was given a problem similar to this but with temperature of the film included. is that of any use?
Thank you very much very very much❤❤❤🎉
sir generally gradient means rise/run, then velocity gradient means it should be l/v na ???
P.s could u explaine why the force will decrease if the distance between two plates increased?
Thanks a lot man, really helped me. GGWP ^_^
Thank you
thank you
Plz make tutorials on cosmology. plz plz plz...🙏
شكرا
Thanks
Awesome
Are some of the same formulas used when looking at convection currents in the earths mantle? Looking to see how much force is required to move tectonic plates. I know the viscosity varies with different levels of the earths core. And heat also plays a role too. Thoughts? Or a better place to look at this?
BTW I real like your teaching method here. This was very interesting
What is the relationship between pressure and viscosity?
How did you end up with formula of Force? F=(eta) A (v/l)? Where was this derived from?
I think newton would answer it the best 🐼
How do I get your contact I really like your teaching
Yes
Ur superb
Why does increase distance decrease the needed force?
I know it has been a long time but Force and length are inverse proportional.
Freaking hero
If you have difficulty solving problems on dynamic viscosity then watch the video from this playlist:

Simple explanation in Hindi
Teaching all this to a 8th grader just wonderful
I probably won't get a response, but I just have a question. In the exercise (1.) Does upper plate have a mass? (I was thinking that, as you needed a force to push it) Let's say also we have two plates (P1,P2) which both varies in mass, the plate (P1) with the bigger mass needs more force to make it accelerate (F = ma) to a certain velocity, and the plate with a smaller mass (P2), which means that it needs less force to make it accelerate to the same velocity. As the viscosity coefficient was determined by the equation (η=Fl/vA), then doesn't that mean that the plate with the larger mass would increase the viscosity of the fluid? That doesnt make sense right?
You were right tho-
One year and still unanswered-😂
3 years unanswered 😂
@@ozzyb3354 damn, has it been that long? completely forgot I wrote this, it's been so long that I don't even have a clue of what I'm asking LOL!
@@knugeniv8517 what a story. Years apart
Honestly I wish I had watched this before writing my exams I would have done better. A similar question came
Why was the velocity gradient not negated
A steam engine cylinder has an effective diameter of 350mm and the maximum steam pressure acting on cylinder cover is 1.25N/mm Calculate the number and size of studs required to fix the cylinder cover, assuming the permissible stress in the stud is 33MP.. Take the thickness of the cylinder wall as 10mm. Assume coarse series with dc = 0.84d
👏👏
I have a question why couldn't we say that F = N.A.S
🙌🏾
This may be a dumb question but aren’t the units for viscosity n•s/m^2?
N/m^2 is actually Pa. So yeah, you are both right
I have found u so late😔
4:29 you're just joking bro. Minecraft disobey that
Saviour
I feel like I am watching a khan academy video... good video anyways.
Ok
Hmm
Now easy like water
What is actually difference between viscosity, kinematic viscosity & dynamic viscosity? Then talk about the measurement tools, what are actually measurement tools for these guys? Finally, what is the most accurate between them?
👍👍👍👍👍👍👍
I graduated from TH-cam university of Engineering
Why do you skip steps and not show working...
I thought
Water has Low viscosity (low flow rate) and honey has high viscosity (high flow rate)? Which one is correct? Because this video teaches opposite? Please if you know answer in the reply button because, I'm going to report. Thank u!
Whay
MUAH
could you please consider changing the mic please. thanks
Thank you
