Funny photos post

Posted in Newark, USA by Ulf on November 4, 2008

These are some (more or less) funny photos which I took on Sunday. The first one is from our kitchen (warning, it takes a minute or two to read it):

bild3288The next one is from town. It reminded me of my home village (it’s called “Staffhorst”):

Now about cars: In Delaware, we don’t have a sales tax. People like that. And we don’t have number plates in the front of cars. People sometimes don’t like this. So they put funny things in the front of their cars. The left-hand-side photo reminds me of my fellow students from Magdeburg. The right-hand-side photo looks much like a German plate:

Now it gets a bit scientific. This is how the building next to ours looks like:

bild3295 bild3296 bild3297
bild3298 bild3299
Do you recognize them all? The second one should describe the phase behavior of a mixture of three substances. The third one is also about the Gibbs Enthalpy and how it depends on the mixture. The fourth one reminds me of a fixed point iteration. The last two should be obvious for control engineers ;-). Can you help me out with the other ones?

    Picture number on ist the Deborah number

    In my opinion picture number four ist the
    number of trays in a destillation collumn
    no link ;-)

    picture five
    jD=jH=f/2
    flux of mass and heat (only if form drag is absent)

    Picture six looks well known to me, but at the moment i have no clue, thought something of the derivation of the Boltzmann equation, but couldn;t verify it.
    They are doing quite a lot fluid dynamics, are they?

    Have a nice time in US ;-)

    Hey! You really were a great help!
    I should actually have known about the Mass- and Heat Transfer as we had this in Process Engineering, however the other ones were new to me.

    btw: Due to the number of links WordPress qualified your comment as spam in the first place, but I could recover it. However, the Spam filter says that it has already filtered two messages. Did you write another comment which has not been approved so far?

    Best wishes over to Germany (or Bavaria, if I remember correctly)!
    Ulf
