Chemical Engineering. I mostly work at a plant in Utah that pushes oil out of the ground by injecting high pressure CO2.

[–]CoolHeadedLogician 9 points10 points ago

my girlfriend is a chemical engineer, i had no idea that you guys had to study stress tensors. i am mechanical, but i can imagine several subjects where it would bleed over between our two degrees.

[–]baltakatei 4 points5 points ago

Well, stress and strain of fluids is a big part of Fluid Dynamics which we covered. Shortly after Fluid we studied Heat and Mass Transport. The kinds of differential equations we studied in N-S simplifications resembled a lot of heat and mass transport phenomena. All that is important for heat exchangers, micro fluidic devices, batteries, bioreactor oxygenation, whatever.

We probably studied a bit of what ME's cover, but just different parts (I don't think we covered vibrations, bending of load-bearing girders, or supersonic airflow around a wing).

    You're worrying me.

    [–]Sisaac 3 points4 points ago

    Be worried. Be very much worried. Then comes rigorous Fourier's Law and non-steady systems. Also Navier-Stokes in spherical coordinates is much more of a bitch than this.

    [–]baltakatei 2 points3 points ago

    It's not that bad, unless you have to derive it in spherical coordinates (I've never done that before). Our class just derived it in Cartesian coordinate and then usedthe reference tables in the back of Bird, Stewart, and Lightfoot for spherical and cylindrical coordinates.

    Edit: fixed drowsiness-induced error

    [–]Sisaac 1 point2 points ago

    The 2nd degree non-linear partial differential equations that you need to solve in order to characterize a system, even when you chunk down one coordinate or two, and make a few assumptions, they become a pain in the ass to solve numerically (don't even dream about doing that analytically), even with a 13rd order Runge-Kutta method.

    [–]baltakatei 2 points3 points ago

    Hmm. I'm not familiar with how the Runge-Kutta-- zzzzzZZZZzzzz

    [–]dynothol 0 points1 point ago

    Or you could just use finite-element software like a sane human being. Besides, you'd have to convert the equations all the way to ODEs to use a Runge-Kutta method, and that is usually not possible.

    EDIT: I guess you could reduce down to 2 dimensions and use the method of lines or something and still use a Runge-Kutta algorithm, but this will still only work for a very simple system.

    [–]patsmad 0 points1 point ago

    I derived it before in spherical. Pretty fucking hilarious actually. The teacher did it because he thought it was worth it to understand why everyone just copied it down.

    Took me a whole night. Eventually I got it truncated to around 5 full pages. For the record this was graduate level Fluids.

    [–]demerdar 1 point2 points ago

    ... navier stokes is an unsteady system

    [–]Sisaac 0 points1 point ago

    But most of the time you see NS for the first time, you dismiss the time-dependant part of the equation, since most of the problems in basic ChemE fluid dynamics are in steady state. When time is introduced as a varible, then... it pretty much fucks up a lot.

    [–]baltakatei 0 points1 point ago

    Yeah, I heard that one of the entrance exam problems that MIT gives ChemE graduate students is deriving the Navier-Stokes from mass, force, and energy balances. So... good luck with that.

    [–]patsmad 0 points1 point ago

    I was trying to decipher your comment. Do you mean into grad school, and do you mean the qualifying examinations?

    I've done on of their numerical methods qual questions for ChemE. It was difficult to be sure, 2D flow down a plane with mass exchange with the surrounding gas solved using finite differences. It gets a bit insane pretty quickly.

    [–]dynothol 0 points1 point ago

    This is not true. There is no entrance exam, and the qualifying exam is open book so this question would be rather easy because you would just copy from a transport book.

    [–]Caloooomi 0 points1 point ago

    It is continuity equations then balancing it out iirc from hmmt. Doing fluids 4 this year in uni, I'm sure I'll see it all again. :(

      [–]swollencornholio 5 points6 points ago

      Well there are typically so many assumptions, it just all gets cancelled out. For instance a Poiseuille Flow that is 2-D, incompressible, and steady state would reduce to something like this.

      [–]cockpitatheist 4 points5 points ago

      I can't believe that even four years after getting a D in Aero-thermo and subsequently changing majors, I still understood all of that.

      [–]pokersjokers 2 points3 points ago

      And then you realize there's CFD programs which can solve it all for you. And then you realize you're never going to do CFD again anyway.

      [–]demerdar 1 point2 points ago

      devil is in the details my friend. if you don't know what you're doing using CFD then you are probably going to get incorrect results.

      [–]Average650 10 points11 points ago

      hmm that look like incomprehensible to me. Seems rho has been assumed constant so it's outside all the derivatives.

      [–]TuxingtonIII 6 points7 points ago

      As a computer engineering student, I worked with a program that computed this. I had no idea what I was doing.

      [–]Bortjort 13 points14 points ago

      Mhmm... yeah... yeah... I know some of these words

      [–]Tactical_Toaster 4 points5 points ago

      The equation is for incompressible fluid flow, like water, mercury ect... and rho is the density of the fluid. If the flow is compressible then the density changes with time so rho cannot be assumed constant but in this case density is constant and factored out of all the partial derivatives in both the u and the v directions which correspond to x and y respectively

      [–]MereInterest 2 points3 points ago

      Why does this post keep being made? You are rejoicing in ignorance, rather than asking for an explanation.

      [–]techdawg667 0 points1 point ago

      And by some I mean none.

      [–]dynothol 0 points1 point ago

      Don't think you're right about this. For example, the Cauchy momentum equation, which is the most general statement of conservation of momentum and from which Navier-Stokes is derived, has density outside the differential.

      Besides, in general something outside of a differential is not assumed constant for any PDE (or ode). eg. if you had the equation xy'' + xy +13 = 0 would you assume x is a constant?

      [–]IShaveMyLegs 1 point2 points ago

      It's horrible that this is familiar to me. I saw that and thought somebody had copied a chunk of my physics symposium presentation.

      [–]MrBlaaaaah 1 point2 points ago

      Navier-Stokes.

      I'm going to use Wikipedia for this because it's got it organized the easiest: incompressible NS in it's general form

      incompressible NS is it's non general and full form Note that the form posted here is the cartesian coordinate expansion of the incompressible Navier-Stokes equation.

      COMPRESSIBLE NS equation

      Now, Wikipedia, as you see doesn't have the complete and expanded form of the Navier-Stokes equations for compressible Flow. So, I got this for you guys: http://i.imgur.com/uayUh.png

      EDIT: I'm dum

      [–]Sisaac 0 points1 point ago

      You forgot compressible NS for spherical coordinates, and extending the divergence of the velocity field. Fuck. That. Equation.

      [–]MrBlaaaaah 1 point2 points ago

      I tried to forget them. And then you came along, and reminded me again.

      [–]Sisaac 0 points1 point ago

      There, there, let a FEM software solve it. pat on the back

      [–]dynothol 0 points1 point ago

      Don't think so...the bulk viscosity (lambda) means the flow must be compressible. How can an incompressible fluid have a bulk viscosity? That wouldn't make any sense, no?

      [–]MrBlaaaaah 0 points1 point ago

      You are actually correct, I was just trying to blend in. SHHHHHH!!!!

      [–]HeAbides 0 points1 point ago

      Does NS only include the three momentum conservations? I thought for incompressible NS included the mass conservation to be complete.

              If you actually go onto proof based classes (higher math to most) then it changes quite a lot, you no longer pattern match problems and spend pages implementing known algorithms to compute answers to problems but rather prove statements about the structure of mathematical objects, it's way more awesome.

              I remember this final exam I had programmed for a Tuesday at 5 PM. The teacher was waiting for us with a grin on his face and the test papers on the table. Then he said "take one, the exam is due to 7 AM tomorrow morning. Feel free to use any tools you have to solve the problems and to work in groups, if you will." Stayed ~12 hours with some of the brightest minds i've ever known in a classroom full of pizza, soda and coffee, yelling at each other at 5 AM in the morning because MATLAB wouldn't converge to a solution. Good times.

              PS: if you're not studying Chemical Engineering you'll probably never have to do anything with transport phenomena. There's hope for you.

              [–]stubing 0 points1 point ago

              I am going into computer science so I am going 2 steps above cal 4. I don't know what those maths are called.

              Honestly, doing a 12 hour math problem sounds a little fun if it was a 1 time thing and I didn't have other classes to worry about. Then again, my brain would probably be dead after 2 hours.

              [–]Sisaac 2 points3 points ago

              Most likely you're going into formal logic and discrete math. Lovely and interesting topics, and you won't be near a differential equation at all. I'm a Chemical Engineering undergrad who happens to have a thing for programming, so I have learned a few things about those topics myself. Good luck with your major!

              [–]beardpunch 21 points22 points ago

              If I ask why, will I have to have a degree in math to understand the answer?

              [–]lolrsk8s_2 21 points22 points ago

              It took Russel and Whitehead 379 pages to prove that 1+1 = 2

              http://en.wikipedia.org/wiki/Principia_Mathematica#Quotations

              This is what that particular sub proof looks like: http://upload.wikimedia.org/wikipedia/en/f/f5/Principia_Mathematica_theorem_54-43.png

              Yikes. TIL!

              [–]autodefenestrator 2 points3 points ago

              Yep.

              Here is a proof for 2+2=4 on metamath which you can follow all the way down to the axioms (it requires no less than 2,452 subtheorems and involves 25,933 steps; this is estimated to represent about 200 textbook pages).

              (This is the above proof by Whitehead and Russell converted to modern math notation.)

              [–]nowxisxforever 0 points1 point ago

              Holy shit. I think I need to go take some math classes now... maybe.

              [–]rapist1 0 points1 point ago

              Do you seriously think a non metamathematical proof of any calculus from ZF would be any shorter than thousands of pages??

              [–]drsupernerd 12 points13 points ago

              The answer to why it is difficult is actually quite simple. In maths the more simple things are, the less rules that exist for the system. The less rules you have to play around with the harder things are to prove. I hope I answered this in some form.

              [–]smog_alado 1 point2 points ago

              And Russel and Whitehead decided to go for the "yo, lets see how simple we can get this to be" route.

              [–]rtkwe 1 point2 points ago

              Hehe, not purely for shits and giggles or flexing massive brain boners. It was a big movement in their time to try and formalize and define all of mathematics from a few axioms. Then Gödel came along and proved that any formal system no matter how complete had no provable statements.

              [–]beardpunch 0 points1 point ago

              That does help. I guess I just took for granted that if you have one apple and someone gives you another, then you have two apples. The Idea of having strictly defined rules of why that's true didn't really occur to me.

              [–]shiny_thing 7 points8 points ago

              If I give you some nails and some wood, building a table would require some skill, but is far from impossible. If I point you at a cliff with ore in it and ask you to manufacture nails... well, that's a much harder problem.

              Similarly, advanced theorems in mathematics may be quite difficult to prove, but at least they can take advantage of mathematical machinery developed over the course of human civilization. Starting from scratch, and defining things like "one", "plus", or "equals" in a formal, mathematical way can be (and has been) the work of a lifetime. And then some jerk will come along and point out that the stuff you started with as "scratch" isn't even internally consistent, and makes no sense...

                No, it's not. You start with the Peano axioms, define your addition function, and it's only a few quick and easy steps to have that 1 + 1 = 2.

                [–]drsupernerd 1 point2 points ago

                But then you have already added rules to the system, by adding the axioms. I was trying to show the beauty of maths comes from abstract logic, not complicated looking formulation.

                [–]foyboy 6 points7 points ago

                An axiom is just a formalization of a(n) (abstract) logic that we know to be true. All math is based on axioms.

                [–]brewmeister58 0 points1 point ago

                Even they had to make some assumptions somewhere.

                [–]Thinks_Too_Logically 6 points7 points ago

                Depending on which/how many axioms you allow.

                Using set theory (especially the well ordered axiom) and algebra, a college freshman could prove it. The Russel Whitehead "proof" (they didn't actually prove it, though they ended the paper with "you can prove 1+1=2 with this, but you need to define addition.")

                But the problem with their attempt was revealed by Godel's incompleteness theorem which shows us that you cannot avoid assuming axioms and that any system of mathematics must start from assumptions.

                [–]rtkwe 0 points1 point ago

                It went beyond that and said every system has unprovable statements outside axioms.

                [–]rapist1 1 point2 points ago

                No. You are wrong. by any nontrivial measure of proof complexity.

                  as someone who couldn't even pass remedial algebra despite all my effort (my high school was not accredited so I graduated without knowing algebra), I have to say I love math, but I hate DOING math.

                  a crap education pretty much ruined it for me. sucked anything even remotely interesting about it out for me.

                  because now that I failed out of community college and my high school diploma isn't worth the paper it was printed on, I am kind of fed up with formal education.

                  honestly, I still need to count on my fingers just to keep track of counting, and if you have me add or subtract at the same time, I'm gonna need a calculator and a sheet of scratch paper. and god help you if you want me to count by anything other than by ones, fives, or multiples of ten.
