Dropping this here since he has two profiles for some reason:

Cool guy. He doesn't allow cell phones, which I think is good since now you're forced to pay attention and the material is pretty interesting. He starts lecture ten minutes late (on purpose) and usually ends ten or so minutes early (if we have a break about 50 minutes in; if there's no break then we would end 20 or so minutes early).

The two midterms were pretty straightforward and graded very fairly in my opinion. The first one was open book and notes (he allowed digital textbooks aka laptop or iPad but no phones), but he changed that for the second one since the class got really crowded and cluttered and it was hard to proctor. We were only allowed a formula sheet (front and back) for the second midterm. I'm not sure if he'll keep implementing the open book and notes policy, I think it depends on the class size and number of students (and in the end it's all up to him). The questions on the midterms were a little more difficult than the homework problems, but not really by that much. He provides typed-up solutions to every homework assignment so each solution is easy to follow and understand.

Because of the coronavirus situation, he gave us a take-home final that we had 12 hours to complete (8am-8pm). This meant it was open book, note, computer, everything (except the obvious: don't work with other people; not something he could monitor but I hope people had some integrity and didn't do this). I'm not sure if he made the final harder due to the whole weird situation but I thought it was pretty tough.

Overall I thought he was a good professor.

he's cool! very funny and starts class at 10 after the official start time. he was super clear the whole quarter but rushes the last section so make sure you're prepared for that.

Professor Khavepour is honestly one of the best professors I've had at UCLA. This isn't an easy class and the material is pretty dense, but he's a very clear lecturer and he really does his best to break down the concepts to make them easier to understand. His lectures are also pretty enjoyable because he makes jokes and interacts with the class to keep everyone interested, but without getting too sidetracked.
As for the specifics, the class has 2 midterms, each worth 25% of your grade, homework is 10%, and the final is 40%. The numbers are kind of arbitrary though, as he said a number of times that he will look at your progress through the class and he might weight the tests differently depending on your performance each time. He even said that if you missed all of the homeworks and both of the midterms but aced the final, you'd get an A in the class.
The two midterms were very straightforward, and the average was around 85 for each.
My only complaint for the class was that the final was WAY out of left field. Completely destroyed me, one of the hardest exams I've taken. I'm almost positive I failed the final but I still managed to pull off an A.

tl;dr: hard class, great professor, fair midterms, killer final. Take 103 with Kavehpour if you can.

Professor Kavehpour is one of those Professors that you either really like or really hate. For me and my good friends we all thought he was a super awesome teacher. He was effective in his teaching habits, and also restricted phone use in class, which helped to curb my addiction. Find a solution manual and do lots of practice problems, that's how I ended up with an A+. He may be a little rough around the edges. but if you take it as a joke and give him some back it will be an all around enjoyable experience.

Intimidating and actually rude (though he is just being sarcastic most of the time). Midterms were pretty difficult, but if you understand the concepts and do the homework without using the solutions manual, you should be okay. Final was ridiculously hard (I'd love to see what the average was). I thought I was failing the class, but ended up getting a B, so I guess it's safe to say that there was a nice curve.

This is one of those classes where you feel like you're lost the first time you take it and then you feel like if you were to take it again, you'd do fine. Homework is easy considering a quick google search will find you the answer so that's a free 10%. The midterms aren't incredibly hard but can be deceiving so if you just rely on simple concepts like mass conservation it shouldn't be bad. Final was incredibly hard. Who knows what the average was but it would be for a good laugh to see the averages and what I got on it. Apparently, if you show improvement throughout the exams you can improve your grade but I doubt anyone was given this considering the final.

As for the teacher, he has a monotone and can sound quite intimidating at first. His homework turn in policy is quite strict so turn it in on time. The TAs were horrible and oftentimes during discussion the students would argue with the TA and be generally lost.

hard first midterm, easy second midterm, ok final, and lots of homework. you will need your textbook or copy of its tables to look up during the exams. he likes to do jokes during his lectures, but I found only a few of them funny. go to his office hours and he will be really helpful.

His exams can be pretty tricky, but if you actually understand the concepts, they can be fairly simple. I screwed up on his first midterm and received a 27/50 on it; later finding out it was pretty straightforward. So, on the second midterm, I thought more simpler and got a 50/50 on it. Key is not to overthink the problems on his exams and you'll do fine. He has his own grading system and if he sees improvement, he'll take that into account when submitting grades. I got an A- in his class.

His lectures focus mainly on the theory behind of fluid mechanics.. It's not essential that you memorize everything he tells you in lecture, but you should go because it saves you a lot of headaches when trying to understand the homework later. The TAs handle all the example problems, so make sure you go to discussion if you need help with the homework. He's a really nice professor who seems to genuinely like teaching and helping his students, so make sure to go to his office hours if you're having trouble. He tends to give much more homework than other professors, and it can be quite challenging at times. He lets us bring our books, notes, and homework to the exams. The midterm is difficult, but don't worry about your grades on the homework and midterm too much. Because Kavehpour pushes you so hard, you leave this class learning a lot and you'll end up getting a good grade if you try to really learn the material.

Hard professor. His lectures are basically derivations; he does no examples in class. The tests are tricky, not hard if you know whats going on, just really tricky. I bombed the midterm but he was nice enough to let me pass the class.
