Thread: 200 geos to solve my engineering question

  1. #1

    Default 200 geos to solve my engineering question

    i know that fluid resistance varies with the square of speed. (to go twice as fast requires 4 times the power, 3 times as fast requires 9 times the power)

    but i'm looking for a corolation between air and water resistance. i know that besides the fact that water fills a vessel to a level and air fills a vessel to an even pressure, there's virtually no differene in their behaviours. water is esentially VERY thick air.

    can anyone find a relationship between the power required to travel a certain speed through air vs the power required to travel the same speed through water?

    i'm looking for a website that i can reference for a report, thanx.
    i'll pay out to the first user that posts a link that i end up using in my report.
    payment to be made before or after reset, your choice

    this is not doable by only taking the pressure into account? for thats essentially the only difference between the 2?

    nah ignore me, im probably babling away

    The relation is approximately the density ratio (air density/water density).

    the trouble is i can't quote "mimik, google earth war forums, nov 23, 2005"

    i need an actual web site to site in my references.

    ok ozzy that was basically what i needed, but the strange thing now is.......

    .......i can't remember why and how i wanted to put it into my report. HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA

    at the time it seemed like a good idea but now......

    good thing i'm working on this paper ahead of time.

    well, what it boils down to is this:

    dolphins shouldn't be able to swim as fast as they do. they have a "magic" skin texture that allows them to do so.

    top THAT!

    Hmmm perhaps not the most complete body of work around. Timmetie circa 2005. Known for spurts of self stated "brilliance"

    for instance;

    Also for well educated responces to current affairs issues

    for example;

    And for enriching the lives of others

    as in;

    Could he be gay (not that there's anything wrong with that)

    Queer eye for the straight guy?;
