New research is showing that it's much more important how hard you're working than how "quick" you are at understanding things. Props for going out of your way to learn! And you're welcome.
Are you able to findout aniroid barometer efficiency in joules terms Are you do this whole work in terms of joules so we found how much work done and how much maximum heat we can produced by zig zag motion of outlet pipe Since hot water is required now a days
You are amazing! Your videos are amazing and I feel like as if I am teaching myself. Your little quotes like 'wait a sec' 'oh did you see that!!!' 'Italian....italian' are funny and helps me stay awake and pay attention! Thnks a lot.
hello ...thanks for sharing man. However what happens if at point 2 the pissing bottle wasn't exposed to the atmosphere? Say it flows through a pipe and we wanna know how much pressure the fluid would exert at say the end of the pipe (not exposed to air) but attached to a manometer or Cork?... if we were to measure this pressure at this point, what would it be?...certainly it shouldn't be atmospheric right?
Thanks for ur video .I Wish i would have teacher like uuuu.......i got my doughts clarified .The question possesed by george thomas is really interesting.
this video was very nice, also if you took that A*v1=av2 u can know the v2 in function of the areas so u dont have to suppose that v1=0. Thanks for the video
I got a question like this on a test but with a small difference: Calculate the flow rate at the hole (area of the hole and height in the tank given), when there is a layer of oil above the water. The total height of water and oil are given. What should I do with the densities?
Why is the pressure the same at 1 and 2? Surely the pressure at any point along the horizontal distance at y=0 is affected by the weight of the column of water above it? So it seems intuitively, at y=0, that you have the pressure of 1 atm acting in the negative horizontal direction (left), and the pressure produced by the weight of the column of water above y=0 acting in the positive horizontal direction (plus 1 atm). So how is the resultant pressure the same at 1 and 2?
I don't understand how they can be the same though. It seems that the pressure at 1 should be greater than that at 2. I don't think you're wrong because the exactly same explanation is given in my textbook.
+George Thomas He is looking at the pressure exactly outside the hole. Because the pressure outside the hole is not in the body of water then it is equal to the atmosphere (his label for P2 should not be drawn inside the can). You are right though that, in principle, pressure at the bottom of the can is greater than the top due to the weight of the water
That's a very clear explanation thanks. I think I understand it now. For a small column of water just inside the hole there is a pressure difference due to the weight of the water above which causes the column to accelerate. Just outside the hole there is no pressure difference so the column moves at a constant speed.
The last minute and a half of this video was so great I felt compelled to find a question to ask about the video: In this case of the purple container-brown liquid situation, what you're (technically, Torricelli) saying is that the height of the liquid in the container as it falls will always match that of the height the "escaping" liquid peaks at, correct? So long as there is liquid "escaping"
I'd say that the hard part was the assumption about the pressure at the hole. It was a good assumption, but I wouldn't have been so certain about it, which is where the value of actually doing experiments comes in.
In the Bernoulli equation, you used y1 as the height for the liquid in the container. Wouldn't it be more appropriate to use (y1)/2 as the height because that would be the center of mass of the liquid?
Doc, shouldnt the pressure at the hole be pgy as the pressure from the liquid above it is 1atm + pgy and that outside it is 1 atm why do we always consider the pressure outside the container and not what is from the inside
The Bernoulli equation is derived using the conservation of energy.The energy within the fluid consists of pressure energy, kinetic energy and potential energy. Kinetic energy is 1/2m v squared not 1/2 Rho v squared. In this case the velocity of liquid within the tank is zero and the kinetic energy therefore is zero.But Bernoullis eqn is written incorrectly.
That got very....energetic toward the end.
ikr. its fun to watch
He love physic

Are you do this whole work in terms of joules so we found how much work done and how much maximum heat we can produced by zig zag motion of outlet pipe
Since hot water is required now a days
Do this calculation for herons fountain ⛲
Do this work for heat provide capacity increases without any fuel by increasing outlets pipe so zigzag that we are getting hot water at another end
your teaching style is very .. legendary, unique, powerful and original !! Please never stop making videos ! EVER !
lol, suddenly he's got high at the end.
i wana study like that :) with that enthusiasm, interest and energy :)
I didn't think studying for a physics test could be so fun haha. Your energy and enthusiasm is refreshing!
Elisabeth L the g there is gravity right?
@@belarminoaron8988 yes it does
This was so awesome I had to watch it twice
Thank you!
Thank you for making sense of everything that I'm supposed to be learning in lecture.
You are amazing! Your videos are amazing and I feel like as if I am teaching myself. Your little quotes like 'wait a sec' 'oh did you see that!!!' 'Italian....italian' are funny and helps me stay awake and pay attention! Thnks a lot.
I LOVE YOUR ENTHUSIASM !!!!!
Better than Indian textbooks.
The energy @ the end lol
Well, I might be watching this 3 years too late, but this is a really well made video! Thanks, Doc!
this really helped me out tremendously! i need to know this for my fireman exams comming soon!
your enthusiasm is super hilarious!!! you've got yourself a new subscriber!!
Please upload more classes
i love ho excited you got about the whole freefall thingo haha
One year later this video was posted, actually an Italian saw it.
Proud to be your compatriot, viva Torricelli.
Yay, Italy!!!
I wish my teacher taught like you do
wow I''m slow at understanding stuff but i understood right away with your video!
and yes I feel good about this now. Thank you so much :)
Thank you so much for this! I might survive calculus because of this video.
Yules the g stands for gravity right?
Excellent, great passion!
He really is Italian, isn't he? :P
Great video. Thumbs up! (Y) Really helped since I missed a class on this.
Thanks a Lot Doc..!! Helped me for my exam prep.!!
Great video, thanks man!

you are aweosme bro :)
Old but gold
Very helpful video made me understand law of efflux easily
Bro you are kind of physics teacher I need
So enthusiastic. Loved it!
ikr
U were amazing sir!! Thanku for the video.. Your energy is at another level at the end!😂
Oh man great enthusiasm
you sir, are awesome to listen to!
You're too kind!
i've missed all classes and he is helping me to pass the test lol
This guy is amazing
God I've never enjoyed a tutorial like this at a point I started clapping my hands and jumping up 😂😂
You just earned a sub for that enthusiasm! Nice video :)
good
hhhhhhh
Wow man
You are awesome at teaching
5:09 I started laughing and I couldn't stop
What about the second formula ?
Effective....Big thanxx...
this video was very nice, also if you took that A*v1=av2 u can know the v2 in function of the areas so u dont have to suppose that v1=0. Thanks for the video
i am just happy that you are happy
Nice explanation
thanks a lot .It is very simple prove but very trike

I hope you are our teacher in physics
pissing bottle lol
very interesting video well explained and the end was fanny ! I really understand it.
Exactly brilliant you man
you r my life saviour
i will perform best in the tests
thanks....
liked + subscribed
That was so good..
Thank's
Even 1 cancels on both sides at 5:13

I like your class

Yup! Barring friction. How many times have you seen sqrt(2gh)?!? Really, it's just MEi = MEf.
Oh, did I say ALWAYS? I mean, only if the spray is directed straight up.
...and then only if the rising liquid is not also colliding with falling liquid that rose earlier (the fountain effect).
Thanks a lot sir
U are an awsm teacher Thanks for the video
love the way u teach 🤣🤣

thank you
Are you able to find out aniroid barometer efficiency ?
Very beneficial
Amazing law of efflux
but as the level of water eventually go down, will it still go to original h or the new h that the water reached? thanks
Thank you for this video. :D
Dude you’re awesome
thank u it help me a lot it was fun
In the Bernoulli equation, you used y1 as the height for the liquid in the container. Wouldn't it be more appropriate to use (y1)/2 as the height because that would be the center of mass of the liquid?
Lol you´re so funny¡ Thank you so much for the video.

Doc, shouldnt the pressure at the hole be pgy
as the pressure from the liquid above it is 1atm + pgy and that outside it is 1 atm
why do we always consider the pressure outside the container and not what is from the inside
That was spectacular! Why aren't you more well known?
'Cuz no one cares about Italians anymore. Dang it.
I’m here because of Dr. Stone
Same, but the video was very interesting.

Damn that was good!!
that was amazing... I can remember it.. I didn't understand in class as I was playing... haha now.. problem solved

Watch till the end AHAH
thnks sir i understood
aww baby g XD I'm defo gonna start calling it that
Neat law and proof, but the master, Swiss Mathematician, Bernouilli, is required for the proof so lets applaud him too!
that was so great,I rily like the way you make jokes while you teaching owesome
respected sir....what's that obsession u got with Italy?
Or maybe it's the obsession Italians have with fluids...
Maybe😎
damn Italians...
mozzarella is based on milk - a fluid -, after all...
Chhavi Gupta nice
this is as funny as it is educational
Dude you rock my socks off! I'd ask you to marry me but I saw the wedding band... sigh hahahaha
Genesis Landestoy My wife chuckled when she read this. Don't worry, though. There are plenty of nerds out there to go around!
cool
U r awesome
LMFAO XD Pissing Bottle D:
Thanks for your help D: Really Appreciated
