Very informative videos. I wish more professors would take their time to fully explain concepts that require a lot of assumptions. 15 min long video that did a thorough job of explaining step by step. Really enjoy watching these videos as a refresher. Thank you.

I am first covering what I teach in my undergrad fluid mechanics course, which I am teaching this semester. We do not cover Chapter 13 (open channel flow). I will teach various short portions of Chapter 12 (compressible flow), Chapter 14 (turbomachinery), and Chapter 15 (CFD). After my course is over, I plan to fill in some of the parts I left out, but at a slower rate - trying to create one video per day is exhausting!
At 3:41 you present another way of writing the Navier Stokes, using the product rule. Do we expand that new term you presented from the inside to outside i.e expand the inner derivatives first or the opposite way, because I get different results?
You can expand the combined term out and rearrange to get the two circled terms. It involves some algebra with the product rule and reverse product rule. The two circled terms ad the combined term (under "These two terms can be written as") are the same, just expressed differently.
The best way is to work backwards - then you don't have to use reverse product rule. Thank you for your comment. Please tell your friends and colleagues about my TH-cam channel where there are more than 460 free videos about the Bible, fluid mechanics, science, math, statistics, air pollution, and other topics. I would greatly appreciate it.
I do not go into that much detail in my course. Net Positive Suction Head is discussed in detail in my book, Chapter 14, but I do only a little turbomachinery in my fluids class and in these video lessons. Perhaps at some later date I will go back and fill in some of the sections of the book that I did not cover.
PDF files for each video are provided. Read the details of the video and you will see a link to an excel spreadsheet that has all the lesson notes in PDF format.

Really liked your videos , Looking forward for some important exercise questions of cengel cimbala book
This video is incredible, you helped me so much.
Thank you. Please share my TH-cam channel with friends and colleagues so that others are aware of this online resource for students.
Please Professor, can you demonstrate using CFD and the steps to solve a typical question.
Thank you.
I do that in lesson 11E. th-cam.com/video/XEnZtKUhKYY/w-d-xo.html

A very good and detail lecture 👌 👏

Thank You. How could I learn about derive Navier-Stokes equation in cylindrical coordinates from Cartesian? Is there any book explained it?
Yes, but typically that is graduate level. Books like Panton or Kundu, Cohen, and Dowling go into much more derivation and analysis.

Will you cover the whole subject here sir ? I am also reading from your book alongside,
Thank you 🙏

By the way, please tell your friends and colleagues about my youtube channel so that they can learn fluid mechanics (and other subjects) also.
Ok sir , thank you 🙏❤️💙👍

tried to do product rule and reverse product rule/integration by parts. I couldn't come up with that expression
The best way is to work backwards - then you don't have to use reverse product rule.

Hi sir , can you give a explanation video on NPSH method
I do not go into that much detail in my course.

Perhaps at some later date I will go back and fill in some of the sections of the book that I did not cover.
Can you do one with cartesian coordinates please?
Lessons 11A and 11D are similar and use Cartesian coordinates for some of the examples.
@@johncimbala alright thanks
Sir please make and post lecture about velocity profile of magnetic field ...😊
I WANT PDF
