Applying the Navier-Stokes Equations, part 4 - Lecture 4.9 - Chemical Engineering Fluid Mechanics

Solving for the velocity profile and volume flow rate in pipe flow.

[NOTE: Closed captioning is not yet available for this video. Check back soon for updates.]

This video is part of a series of screencast lectures presenting content from an undergraduate-level fluid mechanics course in the Artie McFerrin Department of Chemical Engineering at Texas A&M University (College Station, TX, USA).

The screencasts have been prepared in 720p HD with accompanying closed captioning for enhanced accessibility.

My inspiration for producing this series of videos has been my lifelong personal journey to understand fluid mechanics and explain its beauty to others in a straightforward way. I have received no external support for this project...the effort is purely a labor of love.

I would like to acknowledge Aashish Priye and Jamison Chang for assistance in developing the materials and preparing the captioning.

Please feel free to share any comments or suggestions.

Best wishes,
Victor Ugaz

You have restored my faith in teachers of complex subjects!!

[lorenzruhl]

I usually don't comment on videos, but you sir are an amazing teacher and by far the only person I have come across who can intuitively explain and simplify a complicated topic like fluid mechanics!

[georgesbreak]

Absolutely brilliant teaching. I have been stumped in a 4th year undergrad class and you have managed to straighten it out within 30 minutes of your lectures. I dont leave comments often but I wanted to send a thank you for all the fluids students that take this course. All love from Toronto, Canada

man I am dancing in joy such great videos wacthed all 4 part feeling confident for todays test instead of being confused like before

[skvetny]

I like your voice Victor, it's very calm and confident. Thank you for your videos, I learned a lot.

[ninamess]

i can not thank you enough for these precious videos i was completely lost in this subject and u saved me thank you so much !

Who else is watching these his videos during the Lockdown.. Here in African we don't have the online resources at home so the lecturers are just sending notes and we are getting a lot of help from these guys even though our data is expensive

[venkateshk]

Simply mind blowing. Idk how I completed all the videos on this playlist in a single sitting. Awesome explanation. Thanks a lot !!!!

Sir, Navier-Stokes helped me solve a problem I use, or wish I used, every day. If I take the straw out of my milkshake most of the way I can drink a milkshake through a straw. So the deeper the straw is the more vac is required. That's basically made me a wizard to every 7 year old. I BARELY only get pieces of this every time I watch but I get a little better every time. I won't be happy until I can calculate the angle of a pipe needed for a given amount of fluid with a known lighter than air vapor that needs to travel opposite the flow of more dense fluid. Or any one of the other variables given the other known conditions. So think of a safety situation in a lower budget developing nation, liquid needs to go down but its vapor needs to go up in the same cylinder with gravity only.

If all teachers were as good as you, we would be 100 years further into the future. Congratulations, God bless you.

I can't believe how easy you've made it sound. Tomorrow's my exam and I had almost given up on these equations. Watching your 'how to apply N-S equations' just once has made everything so clear for me. Thank you. Allah bless.

[brandonskocypec]

these videos are single handedly saving my grade

[yewlez]

10 years ago!! Such a great explanation, thank you so much

[TimurChepiga]

This is pure gold! Thanks professor prof. Ugaz!

[arcrides]

This series explains things a lot better than lecturers did at uni

[gabrielobedfosu]

Sir, I am so grateful for your videos on fluid mechanics. It has given an in-depth understanding to the Navier Stokes equation.
Thanks

[raikuli]

Whoa! Thanks for the journey from conservation of momentum to this point! Great videos.

[subhadeephalder]

Today I learnt what my university professors couldn't teach properly. Thank you very much for these videos Sir.

[Pamobos]

Good job. Very clear and step by step explanation.

[theingegnere]

with the straw's example at the end you've majestically explained Poiseuille flow : D. Great!
