Believe me I just open this channel for any problems on topics for all my subjects and i get thorough understanding from here ..the teaching method pulls all my concentration to ur teaching and from a dumb person to any topic i suddenly understand everything as if u started teaching me from srcatch in a short time Hats off! I wish u were my professor but i acknowledge you as my teacher with all my heart. Even my teacher notes or classrooms just make me confused after listening to them but you..I dont forget anything after hearing your teaching Tyvm for being there for us .
@ 14:26 he said that p2=250000/98000 it's actually supposed to be 250000-98000. I'm pretty sure that's what he meant and just got his words jumbled up. Wanted to clarify in case someone got confused.
This chapter is tough for me, yet doing these questions instill confidence in me, and make me enjoy physics. Thank you for letting me solve questions with you.
Thank you so much for everything you do! These videos are so helpful in preparing me for my physics final. Kind of ironic that a random guy on UA-cam can teach me more about physics concepts than the profs that I am paying to teach me.
I made a bet with my physics 2 teacher. I need a raw 95 to get what I want. Please, have faith in me everyone. I’ll be scouring these videos for hours. I’m not sure if I’ll make it out.
You are a LITERAL god. Thank you so much for first of all existing man, and good luck on whatever you wish to do :D. Now I defiantly am not gonna fail the test coming up in a couple mins.

Thank you so much for your dedicated time to teach! I'm really disappointed that I paid for someone to teach my physics when I can go to youtube and watch yoru videos. again, thank you so much!! I want to support you so do you happen to have a patron or something??
I should pay you for such a great video your ways are simple yet direct your teaching method is complex yet understandable you should consider teaching in a university !!!!
at 26:00 why is that when i use the pressure at B as P1 and the pressure at C as P2 and substitute the values to get the pressure at C(P2) i get a wrong answer :(
Hi I just wanted to ask, that we were deriving the second question and the third question with the same image but In the second one we used 17:15 W=PE But for the third question we used 29:04 W=ME or W=PE + KE Can anyone explain why did we do this?
at 26:00, Instead of taking the value of A and C I instead took from B and C and got the same answer. I did (496000) + 1/2 (1000)(10)^2 = P2 + 1/2 (1000)(5)^2 .. Is this a coincidence or just another way to solve for the same problem?
In the 3rd problem, the arrows for the direction of flow were assumed at the beginning and never reexamined which causes some confusion. The water must be flowing uphill (from c to a) because the direction of flow is always from high pressure to low pressure.
Please Change in Pressure is always P2 - P1. Why is the reverse the case in derivation of the Bernoulli's equation? God bless you Sir for making physics simple.
One thing wrong about watching videos on UA-cam is that you cannot ask and second worst things is that you come to comment section and you find everyone praising that guy
If pressure is force over area, wouldn't that mean area and pressure are inversely proportional? So why would decreasing area also decrease area? Is that like a special relationship where the force overcomes that?
For question 2, what is the distance between points A & B? Without the distance or the amount of time it takes to travel from A to B at 4 m/s, slope cannot be calculated. I am no expert on this topic, but it seems that a 10 meter increase in height over the span of 1 meter would yield a different result than a 10 meter increase in height over 10 Kilometers. Am I wrong? Did I miss something?
U said if height is getting higher then pressure is getting lower that means the velocity is getting higher. If that the case the velocity of water going up the storey building should be getting higher right?
How come for question 3, we assume that the velocity btw a and b will be the same with the same area, however later on it was mentioned that with a high drop there is an increase in pressure which would lead to and decrease in velocity? Shouldn’t the velocity at B decrease?

Actually everyone noticed it but all stayed quite.
This kind of thing would throw me off so thank you
thank you, I was worried because was finally feeling like I understood this stuff and then this confuses the crap outta me
Thank you for clarifying that!

Understanding Swedish mathematician Bernoulis theorem made so simple by respected professor ofJG is admirable u are genius sir great respects on u sir
Organic chemistry tutor is just so good a teacher. Very brilliant
This man is the best teacher we have
Gabi gabi ata ako andito hahaha
(I'm always here every night to watch your tutorial even though we haven't started our schooling yet)
Thank you for deriving equations without differentiating too much.
😂😂😂
🤣🤣🤣
idk why we're laughing but 😂😂😂
😂😂😂
😂😂😂
Thank you! You make things so much simpler and easy to understand. I think I'm going to ace my physics quiz tomorrow!
bro, you blessed my whole first semester in bio-med engineering thank you!
Thank you for this a 1 hour lecture from my professor couldn't teach me as much as you did in 30 minutes 👍
I love how students in the comments cant Express how helpful you are to them
And I'm one of them thank you
physics exam coming up soon too? lol
Yea ;')

i definitely owe this guy he saved my academic i get distinction because of him
You taught this so much better than my physics professor
I should pay you for such a great video
your ways are simple yet direct

you should consider teaching in a university !!!!
This guy saved my term again!
wowwww what a nice explanation and clarification thank you very much
at 26:00 why is that when i use the pressure at B as P1 and the pressure at C as P2 and substitute the values to get the pressure at C(P2)
i get a wrong answer
:(
I found that P decreasing because of an increase in v as the radious of the pipe gets smaller to be counterintuitive at first.
Hi I just wanted to ask, that we were deriving the second question and the third question with the same image but
In the second one we used 17:15
W=PE
But for the third question we used 29:04
W=ME
or W=PE + KE
Can anyone explain why did we do this?
this was INCREDIBLY helpful! tysm
Welcome all engineering students day(s) before exam😂
I'm doing Biomedicine. No idea why they make us do physics first year 😢
more like 10 minutes before
You know right 😂
We are back here
Ah swear bro

GOD of Physics on UA-cam 🙌
at 26:00, Instead of taking the value of A and C I instead took from B and C and got the same answer. I did (496000) + 1/2 (1000)(10)^2 = P2 + 1/2 (1000)(5)^2 .. Is this a coincidence or just another way to solve for the same problem?
great explanation, you know your stuff
Simply AMAZING! Thank you.
you are a pure blessing bruh. thanks
Man u make my life so easy thank u God bless u
@ 4:08 The height of the pipe obviously changes its not a straight pipe
My thoughts are too
at 25:48, why not use p2 and p3 to figure out p3. You used p1 and p3 ???
You will still get the same answer
I think you made a mistake at 14:10, you changed the pressure in the left from 250000 to 150000, as well as saying dividing instead of subtracting.
the height wasnt converted into m, it should have been 0.1 rather than 10. Also I think he just wrote 250 000 except it wasn't clear
Bless the lecturer❤❤❤❤❤
Nice work, helped a lot!
at 14:12, is the 9.8 given? and why and how did he get the 150k?
Awesome explanation 👍 thank you sir 🙏
In the 3rd problem, the arrows for the direction of flow were assumed at the beginning and never reexamined which causes some confusion. The water must be flowing uphill (from c to a) because the direction of flow is always from high pressure to low pressure.
Thank you so much for this one!! 😭😭🎉
Great video thank you!
Can you do videos on linear algebra?
You mean at point 14:37 not divided by 98.000 but minus 98.000 because there’s a plus not a multiply factor there.
This 30min video is enough for bernoulli's equation
You are the best.Thank you so much.
you saved my term
tnx a lotttt!
Please Change in Pressure is always P2 - P1. Why is the reverse the case in derivation of the Bernoulli's equation? God bless you Sir for making physics simple.
Excellent video, thank you very much
great explanation of this equation realizing how plumbing works lol wish I would of started watching earlier ! anyways thank you!
So good ❤. Thanks so much
at 14:34, why cant u use the pressure head, h = p/lambda p = (10)(9800)
One thing wrong about watching videos on UA-cam is that you cannot ask and second worst things is that you come to comment section and you find everyone praising that guy
Suwun yo mas🙏🏻🙏🏻🙏🏻
Thanks alot for helping me to get this equation ❤
at 14:00 where did the density of water (1000) come from?
it is like when you know that gravity = 9.8, you should know that the density of water is 1000 kg per meter cubic.
It's a constant, just like speed of light (c=299 792 458 m/s).
Thank you for your great video
I like that you have said the meaning of some equations.
Amazing, thank you so much brother!
14:41 You made an error with the algebraic operation 150kpa = P2 + 980kpa. It should be 150kpa-980kpa = P2
14:28 should not be "divided by 98000". answer is correct, but it should be subtract.
If pressure is force over area, wouldn't that mean area and pressure are inversely proportional? So why would decreasing area also decrease area? Is that like a special relationship where the force overcomes that?
I like your video bro 👍👍👍
I hope you answer me. How the height of the pipe does not change?
bro love you videos
Perfect video
Can someone explain how the height is calculated and why it does not change?
Very informative
Great job!
Thanks bro, it helps
Useful 🎉😊
your video is really awesome,thank you.
Isn't it confusing ? P=F\A right. So , when the area is decreased to 2 , doesn't Pressure need to be higher normally ?
Great work
thanks for helping

Thhnnkk uu... But why we have to divide with area and volume when derive the equation
in 22:30, how did he get the 1000? i'm so confused. thank u for everyone that'll respond to my comment!!
Density of water is 1000kg/m^3 at room temp
4:24 Why is density 1000 ????????????
Density of water is 1000kg/m^3 bro
