    Classical BSL Transport Phenom. vs. BSLK Introductory Transport Phenom

    Used BSLK in the first possible semester that BSLK was available. Before the semester began, I was very glad that we would be using BSLK, because of the mentioned extra details in the derivations. In my experience using BSLK, the derivations (which I studied thoroughly) allow for a very strong...

    Fick's Law and the Diffusion/Convection combined equation.

    NA = JA* + CA*(NA+NB)/C for a binary mixture. NA is the flux of the fluid relative to a stationary point. JA* is Fick's law, the flux relative to the bulk motion of the fluid? (NA+NB)/C is the bulk velocity of the fluid. But I don't see why this is the case. I don't see why NB should affect NA...

    The union of any collection of closed sets is closed?

    I don't see how this is the case. Let ao and bo be members of [A,B] with ao<bo. Let {ai} be a strictly decreasing sequence, with each ai>A and {bi} be a strictly increasing sequencing with each bi<B. Let the limits of the two sequences be A and B, respectively. Then define Ii = [ai,bi]. It seems...

    Mathematically describe this function

    This should work. T = (2*100)*x/a+sum from i=2 to i=10 of (2*(-1)^(i+1)*Heaviside(x-.5*i+.5)*(2*100)*(x-.5*i)/a-200*Heaviside(x-.5*i-.5)*(-1)^i) -200*Heaviside(x-.5)+200*Heaviside(x-1)

    Mathematically describe this function

    Each rising/falling half interval is .5a long. So. we want H(x-0)*(2*U/a)x-2(H(x-.5a)*(2*U/a)x+2H(x-a)*(2*U/a)x-... This way the second heaviside function cancels the first when it comes into action at x=.5a, and the third cancels the second when it comes into action at x=a, etc. The U/(.5a) is...

    Programs Possible double major: abstract algebra or otherwise?

    I found out I can pick up a second major in math should I elect to take a two semester sequence in abstract algebra. My first major is in chemical engineering. Right now, I plan on taking a two semester sequence in either: 1) probability with measure theory, 2) abstract algebra (Dummit and...

    Best upper level math for engineering?

    I see. Thanks for the clarification! Numerical analysis, huh.

    Best upper level math for engineering?

    Every time I come onto this thread, I really hope to see someone recommend the real analysis class :/.

    Best upper level math for engineering?

    Hey guys, thanks for the replies! I have locked in probability and statistics theory class for next semester. I see that you both recommend numerical methods; I forgot to mention this in OP, but I am already required to take a numerical methods class that has specificity to chemical engineering...

    Best upper level math for engineering?

    Just making sure you know that I am talking about partial differential equations (not the typical introductory differential equations) and upper level linear algebra (not the typical introductory linear algebra). The reason I say this is that I know the normal versions are required in all of the...

    Best upper level math for engineering?

    Anyone have opinions on real analysis and its worthiness as a class for an engineer/possible graduate student compared to PDE/probability theory? Would it be worth it to use up 3 out of 4 technical electives to take all three of these classes?

    Is This Spring Schedule Too Challenging?

    I'm going to go out on a limb and guess that "Basic Math" is not simple algebra or something like that. It's a junior level course, haha
