We would love to, but it takes a lot of time. We first want to create a set of videos that discuss concepts and derivations. Worked examples with numbers may be created in the future.
CPPMechEngTutorials I understand, can you recommend me web sites with exercises or good books? currently im using the book fluid mechanics by cengel but I al ready did all the exercises of fluid statics. Thanks for the help!!
what if the magnitude you are trying to find is the water force over the length of the wall from the top of the surface to the bottom? That is the point where it is very confusing to me.How can you instantly tell that oh Im gonna use Rx=Px(A) for the horizontal component and Ry=(density)(g)(Total Volume)? How can you draw the FBD for what it is asking? Im reading different books to take the Mechanical FE and in one book it explains the average pressure of Px=(1/2)(density)(g)(h1+h2) however in the FE manual it doesn't dictate the *average pressure formula. So how do you know when to use it at a certain component?
Can someone please explain something to me? We know that pressure acts perpendicular to the surface. Thus, the force that exerted on the wall should have both the components of x and y. But in the video, it seems to me that he only considered the weight (y-comp) of the fluid but not the x component that the fluid exerted on the wall. The only x component considered is that of the external pressure by the surrounding fluid, but not that of the fluid body in question. In the y direction, we have F1 and weight, in the x direction we have F2 only. Are we not supposed to have another force in the x direction?
Max Payne bcoz fv is balancing the net force of F1 & W and hence will act between their line of action . And for Fh, since it is only balancing F2 , therefore it will act in the same line of action as Fh.
If a circular plate and a square plate of same diameter and side "D" m are lying vertically in such a way that their center are "D" m below the free water surface. Find out the ratio between the total pressure and centre of pressure between the circular plate and the square plate.
Yes, but the atmospheric pressure is approximately constant around the entire system. So the downward force on the free surface is balanced by a similar upward force on the gate. The atmospheric pressure forces cancels out, so we ignore it.
derive the analytical expressions the magnitude and location of the horizontal component hydrostatic force acting on the curved surface ? this is a question that I cant find the answer please give me some help
So I have a question... y did u calculat the area in 8:25 for Hs only .. I think u shoud calculat it for all Yr .. right ? please someone explain to me why? many thanks.
Gazi Gn he has calculated Fh by multiplying pressure with area and Fy by simply the weight (weight itself is a force u don't need to multiply it with area) carried by the surface.
Hi, I want to ask that when you mentioning the weight, which weight are you considering, (a) the one for the isolated body of water or (b) the one above the isolated body of water. And if it's (a) how do we find the volume of the that shape that has such dimensions.
Great! All our videos are captioned to help people with hearing disabilities, people who are non-native English speakers, or people who prefer to read text.
lol i have an exam in 10 min. this video better come in clutch
Lmao me rn
Did it?
@@CPPMechEngTutorials it did, I think I got a B+ in the class.
😂
just finished writing my fluid mechanics exam so I can now 10/10 recommend that watching this video an hour before your exam will help you out, thanks

Whoever is behind these slides. Keep doing God's work!
PowerPoint can do amazing things in the right hands.
it helps a lot.thank you very much from Sri Lanka 😊
No problem... from California :)
Very well done and right to the point. Graphics were well made and helped a lot with understanding the concept.
Thanks!
how does this 10 min video explain this better than my 2 hour tutorial? good job
perfect! this makes it all so clear, compared to what my professor was doing. thanks! :)
This topic is a tricky part of fluid statics. Even this video does not cover all possible scenarios.
Thank you! This video clarifies everything
Great!
short and crisp explanation...thank you for this...
Why F1 acts at centre it should act at centroid right

thank you . missed my tuition class helped me so much
You just goes directly towards your notes and didn't explain how the horizontal component hc and A are solved...?
Please do more videos but only with exercises, very good and clear!! Subscribed

If you completed all of the end-of-chapter problems on your own, you probably know the subject matter well enough.
is it correct to calculate Fv like this video? th-cam.com/video/Awp-iP3ktDI/w-d-xo.html
because its different from yours
fantastic explanation, thank you so much!
:D

thanks! It helps a lot
Glad it helped.
Thanks a lot , I have an exam today.... and the video explained to me in 10min what I had been trying for 2 days 😂
Great explanation! Thank you very much!!!!
I finished my engineering degree early this year I just come back sometime here to remind my self of how lucky Im passing that crazy class :)
Luck, or skill?
This is amazing! Thank you so much!!!
You're welcome!
that could take a 3h lecture with our professor

what if the water is underneath?
hanks for the video it's preferable if you give an example
Currently this video series focuses on the theory of fluid mechanics. Eventually we may add examples.
@@CPPMechEngTutorials This series would be perfect with some concept questions to solidify the given theories.
Very helpful! but why is Fv and and F1 aren't on the same line of action?
Why Fh and Fv have same line of action
Max Payne bcoz fv is balancing the net force of F1 & W and hence will act between their line of action .
And for Fh, since it is only balancing F2 , therefore it will act in the same line of action as Fh.
@@krishanveer8199Great Explanation
If a circular plate and a square plate of same diameter and side "D" m are lying vertically in
such a way that their center are "D" m below the free water surface. Find out the ratio between
the total pressure and centre of pressure between the circular plate and the square plate.
Mera to set dukh ne lag Gaya
Is there force exerted by atmospheric pressure in the vertical direction? If not why?
Yes, but the atmospheric pressure is approximately constant around the entire system. So the downward force on the free surface is balanced by a similar upward force on the gate. The atmospheric pressure forces cancels out, so we ignore it.
Thank you. I just had the same question. 4 years later !
Thank you!
❤️❤️❤️
Damn! Unbelievable explanation!!!
I know, right?!?!
Does F2 and Fh always occur in the same line of action? Thanks for the lesson.
Yes I think so. It says the same in Cengels book
if they dont their moment about O isnt gonna nullify each other (since F1 = Fh)
Best three videos on the same topic. 4.1, 4.2 and 4.3 all were really goood
Thanks! It took a while to make them (all those years ago).
Why isn't this taught in ME 3111?
Nice one......explanation ok
Just okay? :(
Learning the same thing in class but why does this video make 100x more sense ?? I don’t even know..
Only 100x? :(
You fucking explained it better than my shitty professor. I love you ❤️
We're fond of you too.
what happens if you flip the figure?
derive the analytical expressions the magnitude and location of the horizontal component hydrostatic force acting on the curved surface ? this is a question that I cant find the answer please give me some help

Hi, I want to ask that when you mentioning the weight, which weight are you considering, (a) the one for the isolated body of water or (b) the one above the isolated body of water.
And if it's (a) how do we find the volume of the that shape that has such dimensions.
It still has water in it, you're just drawing an imaginary boundary to make a "container" you can analyze.
Thank you sir, your video has been wonderful 🙂
Glad you enjoyed the wonderful video. :)

will inclination angle depends on hydrostatic force
Absolutely, theta=tan^_1(Fv/Fh) so as the forces change so does the angle
How is the Area Ws*Ls?
The 3D body explains it in a way, try imagining it... 2:57
Yep got it
what is the value of "d"? ty
"d" is the depth where the curved surface begins.
thank you sir for making its so easy
You're welcome.
I just asked doubt manner..
"doubt manner"?

is f1 equal to the moment arm of fv?
No. The moment arm of Fv is a weighted average of W and F1.
@@CPPMechEngTutorials how did you get moment arm of the weight?
great one.
Thanks.
thanks alot
No problem.
Thank You.

its easy to understand ...thank you
this makes it way harder then it needs to be
I was so close to going to Pomona, guess I ended up going there any way through these videos!
It's never too late.
