    Young Chemical Engineers needed for AIChE Focus Group

    Is the trans-Atlantic flight included? :-)

    Summer Experience for Engineering Student?

    Of course you can get a job as an intern in a big company. I found (as a student, and as an engineer now) that often those are very much aimed at the demands of the university. Since you're interested in a nice summer job, for which you will not receive a grade, I suggest you actually search...

    Which Heat Exchanger Is Best for Rapid Cooling and Easy Maintenance?

    I'm in need of a specific heat exchanger (a quench cooler). It needs to cool fast (in seconds) and it needs to cool a lot (hundreds of degrees). The coolant is water (making steam). The other side of the heat exchanger is a gas which can be compared to an exhaust gas: there are particles...

    How Do You Calculate Flow Rate and Heat Transfer in a Semi-Circular Pipe?

    Q= (Pi (P1-P2) R^4)/8uL First of all: always write down what the symbols mean. Now I have to guess, and that's not helping. If I make a mistake (because I use other symbols because I live on another continent perhaps) we waste time. Assuming that Pi = 3.14 (-) P1 and P2 = pressure (Pa) R =...

    How Do I Format This Excel Equation Correctly?

    I didn't bother to do any algebra... but indeed, if it is important, writing out an equation on paper before entering it into the computer generally makes life easier. Equations in a computer program can become a nightmare with all the brackets and pluses/minuses. I'd be surprised if Excel...

    For an equimolar solution of n-pentane and n-hexane

    I think that the law of Raoult is the one you want to use... but I am not certain that you have enough data for question c). I'd expect a volume and a total amount of solution given there.

    Use of computers in chemical engineering

    I'm a chemical process engineer, and I use the computer every day. I make computer models of big chemical factories, I sometimes run detailed simulations of parts of the factory (reactors, separation columns, other pieces of equipment). My work does not include control systems, but that's even...

    Packed tower problem (gas-liquid absorption)

    First, I am not sure what you mean with the Y*=1.75X. Is that an equilibrium relation? Which phase is Y, which phase is X? One is probably the water phase, one is the air phase. Convention is that X is liquid, Y is gas... so I'll go with that, although it should be specified next time to make...

    How Do I Format This Excel Equation Correctly?

    Well... my excel does not understand "QUOTIENT" (I have an English speaking Excel 2003). And also, there seems a mistake in your formula: ([R^4-(R-λR)^4])/([4λR^2 (R-λR/2)^2]) - the underlined part, should I subtract one part from the other, or multiply? There's a symbol missing. I chose for...

    Comprehensive Guide to Mechanical Device Properties

    What you want is to learn chemical process engineering in 1 simple step. I'm afraid that it's not all that simple... (Almost) all of these devices have "ideal situation" equations... but those almost all again depend on the mode of operation (are you having a gas, liquid?... is it...

    What advantage of oil in hydraulic brake over air?

    Air, and any other gas, can be compressed, while oil and other liquids can be considered nearly incompressible.

    Can kg/m2h Be Converted to m/s for Process Calculations?

    Hehe... you probably shouldn't. On internet you can never be sure you're talking to a native English speaker (who can be expected to choose exactly the right words) or someone (like me) who is merely likely to choose the right words :D

    MATLAB Buy Matlab for Your Engineering Studies

    Since the Octave code, for simple homework calculations, is the same as Matlab, I'd just download Octave for the time being. It will in 99% of the cases mean that you can run the scripts also at the school - or if your online teachers will want to see and run the script, it should work. If you...

    Can kg/m2h Be Converted to m/s for Process Calculations?

    kg/m2h is a mass flux of a substance through an area m/s is the linear velocity of that substance Therefore, step 1 is to convert the mass flow to volumetric flow (divide by density). then you'll need to realize that: m3/m2h = 1 m/h so, the volume passing through an area per time equals linear...
