This lecture series was recorded live at Cal Poly Pomona during Fall 2014. The textbook is Munson et al., "Fundamentals of Fluid Mechanics (7th edition)."
Holy moly! Lectures from Dr. Biddle! I took as many classes as I could from him when I was at CPP. He had that rare combination of being extremely knowledgeable, extremely patient, and mastery in the art of teaching. If you are trying to build a solid foundation of understanding on a topic, he's the guy. He needs to be cloned and distributed to all schools.
That's why we recorded him. Fortunately he was eager to be recorded.
@@CPPMechEngTutorials Please do more courses FULL COURSES PLEASE. If also Mathematics course (Algebra, Calculus 1,2,3 , Ordinary and Partial Differential equations, Mathematics for Engineering, Computational etc....) also I would like if AutoCAD and MATLAB AND PLEASE CONTROL COURSE IS MUST.
THANK YOU
I'm sold. I'm watching this entire series
Mastery of handwriting, even on a wall board!
@@CPPMechEngTutorials wow , he is the best, all the way from South Africa, I am benefiting from his lectures, big time. The simplification of complexity is mastered by the Prof. Thank you for recording him.
Preparing for Thermal & Fluids PE. Didn't realize how much I've forgotten. Excellent video. Also, a note to those that are post-grads (such as myself): Don't fall into the trap of thinking you're better than watching undergrad videos. 4 years of working abstract derivations (i.e., derive navier stokes in a spherical coordinate system with xyz conditions) is great, but for PE applications, many need to dust off the calculator every once in awhile. Excellent series.
can't believe i come across this series again. i skipped all the fluid mechanics classes and this lecture series was the only thing that helped me passed that damn course 6 years ago. angelic content
hahaha in the same boat, got my exam on the 11th. Some things never change
Hi quick question, does Dr. Biddle's 19 videos in this fluid mechanics 1 playlist teach everything that was in your fluids class? Cause I'm about to take my class this fall and we will meet up 3 times a week for 4 and a half months straight. Or is Dr. Biddle that good that he can summarize things in a much more efficiently and thus took less time to discuss everything? Thanks
That feeling you get when you realize your whole semester is saved! Looking forward to watching this whole series, thanks for the great video!
Did the lecture series save you?
@@CPPMechEngTutorials YES! Passed with an A and know it like the back of my hand. Went on to study Aerodynamics my senior year and was well prepared. Time to start watching the Heat Transfer series!
My turn to have my semester saved

Now, when Universities are closed due to pandemic, these kind of courses are invaluable.
Konrad Kacperowski agreed.
Thanks. When we started making videos back in 2013, we didn't expect this pandemic to happen. :P
invaluable? or perhaps priceless!
I'm of the opinion that education should be free and of easy access. Kudos to you :)

I don't know where it was during my grad, but I am doing it now, and I can not convey my respect and gratitude enough for whoever took the initiative to record the lectures. Thank you very much
It was a team effort that took place over many years... and still ongoing.
I'm Currently a 3rd yr mechanical engineering student from Philippines, due to this pandemic students are force to take online classes which is not compatible to everyone but thanks to this channel i can do a advance study prior to my subjects i just finish a video from this channel about heat transfer and it help me alot. I give my thanks and hoping that this channel would never stop uploading videos that help aspiring engineers👍👍
The pandemic has slowed us down a bit, but we will keep working on it.
I really hope you see this comment Professor Biddle. Never ever have I enjoyed a class of engineering like this! I don't know whats your secret for teaching so well, but you're an amazing teacher! I wish you have taught me all my 4 years in engineering college!
Thanks for the nice comment.
Dr. Biddle's lectures are the reason I passed my fluids paper last year. As an aspiring Hydraulic engineer I will no doubt visit this series in the near future. The explanation and camera work is just top notch. Thank you from the bottom of my heart. You guys are the best!!
Thanks!
Such an underrated Professor. By far one if not the best professors I had at Cal Poly...
I wish the newer professors would watch his videos and learn how to teach effectively.
Man this guy kicks ass at teaching Fluids. My Fluids professor knows his stuff but isn't all that great at teaching it. I really think video lecturing is just superior to in class lectures because I can pause and go back if something confuses me.
Took fluids last semester and heat transfer this one, you honestly are providing the best service because instead of kids being forced to cheat in school because tenured professors cannot teach well, you actually explain it well and teach us properly. God bless you man, and thanks for being such a great teacher
Glad it helped!

Dr. Biddle is a very good lecturer. He is very patient in explaining the subject matter. It is much better for him to use the board than some other teachers using the power point. He allows students to follow much better this way.
I love how this lecturer explaining the contents. It's easy listening and not boring to hear due to his cheery-vibed speaking tune
Just would like to point out, the answer he says at 49:37, "the thickness is one ten-thousandth of an inch" is wrong. He meant to say that the thickness is one ten-thousandth of a FOOT, his answer should be 1.17e-4 ft, which is 1.4e-3 in. Otherwise, it was a fantastic lecture.
Surprised no one caught this but it's actually ten times thicker. 11.7e-4 ft = 1.17e-3 ft = 1.4e-2 in = .014 in
That's about 1 1/2 playing cards thick.
I thought I was going crazy 😂. I needed to hear this
Here's your cookie, go away now.
We'll put a correction in the show notes. Thanks.
I watched Dr. Biddle's Heat Transfer course to help with my course last semester. I just got super blessed this semester finding that he has a whole other YT series for Fluid Mechanics.
Thank you Dr. Biddle, you literally are the best.
Thanks!
In the midst of this pandemic, these lectures have simplified my life in many possible ways, the Units at first are complicated if used in US but one has to convert them supposedly. Thank you so much for these lessons, I have improved very well in this module since I found this. Keep it up, your work does not go unrecognised.
We are glad the videos are helping people around the world... even in those wacky SI countries. :P
At 49:17 the correct answer is 1.167 e-4 ft. The lecture was fantastic and informative.
Thanks. A correction has been added to the video notes.
did it 3x and it came to the same answer so I thought I was losing it, scrolled through and found this.
Wow I love how you teach so steadily without rushing key concepts.
I am actually mad for the SOLE REASON that my fluids class took a whole week of 3 50 minute class periods to cover what this guy did in 25 minutes. Love the lecture, I will be referring to this repeatedly thank you for continuing to improve our lives by giving us access to this kind of high level education/information.
Prof. Biddle does an excellent job of getting to the important stuff.
I'm a 65 year old semi retired electrical engineer . I wish I had paid more attention to this subject at university.....this man knows what he is talking about and is a pleasure to listen to.
He's one of our best.
I used this during the Covid-19 Pandemic to keep up with my Fluid Mechanics during lockdown and while online classes were wonky. Thank you so much!
We're all lucky the pandemic happened after these videos were made.
Just in time for the Chemical Engineering Board Exams here in the Philippines. Thank God I stumbled through this channel! Amazing work!
Good luck on the exam!
Thank you so much for making these available! Thank you professor for your energy, and thank you camera man! And whoever involved
You're welcome!
This made me realise that all my lecturers need to go for handwriting classes. Due to their handwriting, half the time we are trying to decipher the handwriting, not the logic behind the study.
I think its pretty legible...
THANK YOU, Dr. Biddle !
How an hour flies!!! I have listened the whole section at one breath without no break, it is AMAZINGLY CONCISE ！I LOVE IT ~~~~
His voice is hypnotic.
THIS TEACHER IS GOOD, very good only in 10 mins of the clip... wish we had more of these at my university
He is a great instructor, I have never gone to faculty :) thanks to him
There can only be one Biddle.
Thank you for the great information. Looking forward to progressing deeper into my studies with this excellent resource.
i get survived and blessed when i have seen your channel . i really wan to say thank you because my lecturer on the uni do not even give any lectures
This guy is 1000x better than my actual teacher. Legend. Thanks for the massive help.
Our pleasure.
Thank you for the video. I am working on a project on poverty reduction and one of the main focus is on the impact of mechanical learning vs actually understanding a concept, in the actual application of theory in real life. Your video is helping a lot, as your explanation is very clear. I am designing an irrigation system and If I make it, I want to thank the whole team who came up with this video.
You're welcome. :)
Yeah thank you very much to the Professor and the University for sharing this with us, but I just wanna take a moment and really 'thank you' to the blessed soul who put down the subtitles for us who don't have English as a first language or for those who have hearing issues.
Even native English speakers often find the captions useful. :)
Came across this accidentally. What attracted me was the dimensional analysis at the start. Great pedagogy. (Have training in Earth science but not an engineer or physicist. Understanding of rheology, petrology, glaciology and meteorology relies on understanding of fluid mechanics.)
i’ve never been jealous of a man’s handwriting ever before in my life. damn its nice
I love when says "ahh the units" and shakes his head. I relate too much, every engineering class its a necessary but tedious portion.
Thank you for taking the time to make these videos and allowing people who want to learn to learn.
Our pleasure.
This is great thank you. I'm about to take my fluid mechanics course this summer and these lectures are a great resource to help me prepare.
Did the videos help?
This is just amazing. Dr Biddle you have really made engineering easy. Thanks. Love from Pakistan
im a mexican student and my course wasnt good so i discovered this one and im glad its pretty good! great teacher, thank you so much for this
¡Qué bueno!
English isn't my first language, but with your explanation I can easily understand this course.
Thank you, from Guatemala!
De nada.
Watching this over summer to ease next semester. Thank You!
This guy's great! Thank you for making this series !
You're welcome!
you have earned yourself another subscription. good job applying your charisma to your lectures. Just by your attitude i would love to take this course from you. and you describe motion in a way that is far more comprehensible than other teachers. thank you so much.
Thanks for subscribing. :)
I miss my college when watch it. It very useful in this pandemic. Thanks for the video!
We all miss being on campus. Fortunately, this situation won't last forever.
Better than any lecturer I've had
He's been practicing for a while. :)
that "a lot" definitely paints my engineering journey in my Uni right now XD . I felt that LOL
"you don't get good until you suffered through some homework." best quote ever.
It's very true.
Wow, that is simply amazing how he engages his body movement while teaching.
This might save my GPA this semester, thanks :)
Did it save your GPA?
I am from South Africa. I just discovered these videos. Thank you very much Dr John
You're welcome!
who is watching this lecture COVID-19 time . after 4 years
You can see views vs. time on desktop
Sir I am from India and preparing for one of the most toffest exam JEE advanced . Thanks sir for your best explanation
We're glad it helped.
My favorite professor when I was at CPP!
Indeed that I am going to resume my Pre engineering courses. But now to decide between mechanical or electrical and computer engineering. I find electromagnetic fields and fluid m3chanics to be ewually interesting, as well as thermodynamics. I just love any subtopic within physics to be honest, from Mechanics to Optics to Quantum mechanics. Relativity and solid state physics as well as particle and field theory. Endlessly fascinating.
This due is absolutely awesome. Hell of a teacher too
he's so charismatic. id love to take this course..even if he assigned a lot of hmwk...itd be worth it.
You don't get good until you suffer through some homework and say: "gosh, I just don't get this!"
Thanks for the great advice Dr. Biddle!!
There is a lot of learn through failure.
I am very grateful for sharing the se lectures. Thank you from Italy!
:)
I absolutely love this guy! wish he was my professor
You sir are an amazingly clear and interesting lecturer!
much love and appreciation from a mech. engineering student from Tel Aviv University
Thanks!
Sir you are like light in darkness ..much love and respect from Pakistan ...❤❤☺🙋
Thank you very much Sir for sharing your knowledge. God bless you more. :)
-regards from Philippines
You're welcome.
Taking Fluid Mechanics this summer. Not fond of math sometimes, mainly due to my attention span. Not sure how I made in this far....ha. But I'm gonna use your videos to get a head start so it is not as grueling as semesters in the past. Thanks!
What text book are they using?
Love your videos sir, You make Fluid mechanics so easy. Thanks and Regards from Pakistan
Our pleasure.
I loved this coursed until he started writting the units in foots and lbs
Yes, we use silly units here in the US.
You just need to do conversion of units. It’s good to be bilingual on these types of units
@@mrcoffee315 Yeah, its good to be bilingual period. But when dealing with data and analytical analysis, it would be a whole lot more efficient if the whole world uses a standard set of units, aka; SI units. We don't need that lbs, slug, etc. bullshit.
It's like learning another language! It's tought, sometimes it sucks, but we have to accept that!
I'm Brazilian and I have difficult with this English units too, but we have to play the game yo...
And for me the most unnaturall unit it is temperature in Fahrenheit. It blows my mind hahaha
Juan Pablo but the scientific community around the world agreed on a common unit for the sake of efficient communication. You can practice being “bilingual” on your own, but using these units is only slowing down the scientific and mathematical processes and adding more room for errors
Thanks for these marvelous lectures by such an intelligent guy ❤
Such a good teacher.
This is REALLY REALLY REALLY helpful. Thank you so much Dr. Biddle. The world needs more people like you^_^.
We agree. :)
It was amazing.
Thanks to the teacher and someone recorded this video
Great teaching. You really made it look easy.
Beautiful! Magnificent! Thank you professor!
Thanks for the Lecture Sir!
Great Work! From Philippines.
INTERESTING, HE didnt use any powerpoint
he's a great teacher.
Agreed!
Absolutely outstanding. I wish I'd started watching your lectures soon!
Better late than never.
Brings back memories, reminds me of how much classes suck! 1 of 34, Ugh!
Great Video John, Thanks. I would have asked for the Students to put all of their homework in Engineering Format too.
IE:
Sketch
formulas
The math for the solution, etc.
Then in the right hand column --->>
I wasn't sure if it would show up correctly ....
Over on the right hand side you would see ANS = xxx units ( underscored) You tube didn't like me underscoring the above suggestion
wish I had Dr. Biddle for more classes. I only had him for Heat transfer ME 415 on the quarter system in 2017 or 2018 I think it was.
This is pure gold. Thank you very much.
Awesome guy
I'm using the exact same textbook for my Fluid Mechanics unit next semester! This lecture should be really helpful :D
Good luck next semester!
HI WHICH TEXTBOOK IS IT FIRST DOING MY FLUIDS COURSE
Hey, thank you very much for your time and help!!!
Our pleasure!!!
I seen the homework problems to the right. Did you assign all those problems ? even or odd only ? or all of them in between ? im trying to prepare for my fluids class and am trying to see which problems to practice.
유체역학은 고체역학과는 많이 다르다고 느껴집니다. 그 이유는 바로 유체를 다룬다는 점에서였습니다. 유체가 무엇인지 어떤식으로 정의할 수 있는지를 이 영상을 통해서 파악하고 적용할 수 있었습니다. 감사합니다.
I really enjoy these videos. Dr Biddle and the derivation videos are very clear at explaining the concepts. Could you post the numbers of the assigned homework problems or the syllabus?
A syllabus has been uploaded to the ME Online website (see link in video description).
just started the video and saw him writing on the white board, I realized I am at the right place. thanks
@cppmechengtutorials
thank you for this lecture - much appreciated. At 49.00: all units of measurement cancel out. From a mathematics perspective 'dy' should have remained instead of 'd'. Therefore 'dy' = 1.17e-4 'unitless' should have remained as the answer. An explanation of 'dy' = 'thickness in ft' should have been explained afterwards - for clarity? Just trying to make sense of this for my exams. Please email or respond, it would be great to hear your thoughts on this.
Got it: 'D' should remained as dy and then all units should have been cancelled out. This will make dy = 1.17e-4 ft
I'm going to buy the textbook and do this entire course. My professor doesn't speak english... Love the age we live in
It truly is an amazing time.
Fantastic job put up here. Thank you
The lecturer is brilliant ✨
What is the name of the book that is used in the lecture?
Sir gg love and respect from Pakistan ... your teaching method is classic ...as well deep full knowledge ...😊👍😊❤️
Thanks!
thank you so much for sharing knowledge may God bless you sir.
You're welcome.
Thanks for these grade-saving lectures! From Dallas
Our pleasure
what a hand writing...and is also great lecture.
I wish this guy was my friend...
Prof. Biddle is a pretty friendly guy.
I'm completely new to all of this but I'm still picking things up
