Hei, crossfire. I am looking for help with my homework in fluid mechanics. I have done my homework, but I have some mistakes so im looking for someone who can guide me to the right path.
My homework
1. calculate the components of the external surface of the control volume A,B,C,D,E
2.calculate the dynamic components of the external surface of the control volume A,B,C,D,E
3.Calculate the hydrostatic components of the control volume in the external surface
EDIT: first 2 question i have answered correctly. 3rd question is 80% right (i think). I only have to find buoyancy of face A.
But now i have 2 extra questions. Ihave to find u1(x2) when 1) Couette flow ( p/x1 = 0 ) and 2) Poiseuille flow (U=0)
For your help, I can give you Dota2 invite, Diablo 3 questkey, money or smth else.

don't have a fucking clue
gl with that !
Etc.
Understanding how things work isn't just remembering stuff, rather knowing it so you can explain it through logic and reason. That being said, fluid dynamics are interesting, your math problem isn't. :D
Though it's been said by some that math is the language of the universe so it's most likely highly useful. But what I said earlier applies when studying it. It's all just remembering formulas and other tools to use math, not really aimed to give you the fundamental understanding of it so you could figure out these things yourself that they teach you to remember.
But you are right about the math part, its not interesting at all.
So as a philosopher I must ask, what is math? :D
At first i was like wtf and then I understood:
Actually, it is more of a rule, than a guideline.
math solves practical problems like does the airplane fly ? or does the sub goes down the ocean with people + still fires ammo ?
can an elevator carry u ?
does a bridge colapses on heavy trucks ?
math as to be teached conceptualy but aplied and adapted exclusively to each problem
that is done by the person wanting to solve the problem and not by a teacher teaching how to solve one problem and tell us to adapt to other problems, that only can be used as a aplication example
not worthless just not able to make comments on this type of subjects, the man asked for help and you replied on how u dislike the modern educational system
"ééééh..?"
"the man asked for help and you replied on how u dislike the modern educational system"
Well, think of it this way then. I dont know the answer to man's question. I can either ignore the whole journal or write something. I decided to write something, that something was my opinion about his problem and I raised questions to provoke conversation. I was actually hoping he'd respond something related to math and/or fluid dynamics but yeah, that was too optimistic of me. It's not like my comment was the perfect to provoke such conversation but it's a start. He could've replied saying something like "yeah, the math problems are boring and this specific problem is aimed to understanding Navier-Stokes equation" which itself was a fine example of what I said earlier in my comment and wanted to add more depth to it. There is still one loose end which is talking about Navier-Stokes, but I haven't gotten into reading much about it YET.
altough now i think i could be a worthy conversation partner, and no, im not a professional philosopher
familiar with what kind of topics?
I could be trying to figure out the speed Jesus had to reach in order to walk on water or does light bend because of space/time fabric or do we have false assumption about linearity of light while in the meantime you might be wondering how fast you have to drive to get to a meeting in time or how long does it take for your tea to cool down so it's perfect for your taste.
I've studied countless topics and concepts each with varying degree of depth and it's simply uninteresting if I've already moved on to a next level of thought in the chosen subject.
ok proceed, your level must be awesome
but there is so much to understand that no human could ever become God, that's why it's so fun to be human, you get to make choices that will decide the course of your experience, "free will" if you will.
Can't help you there since math is a language I'm not very good at, but fluid dynamics in general is a very important aspect to anyone trying to figure out structure of matter. There are lots of stuff written about Vortices, Fibonacci, "Universe's Blueprint", Micro/Macro Cosmos and All sorts of Theory-of-Everything's that are highly related to fluid dynamics. Math is precise while philosophy is broad. To grasp any of this, to really begin to understand, you need both in my opinion. I have ground in philosophical aspect of it, but highly lacking in math. If you're interested in chatting (in english) about it I'm up for it.
but didnt get there yet
gl tho!
