    well actually it takes more pipe if it's curved. plus more sky hooks. lol. does the pipe go through paris, france or houston, tx? or some other path? breid...............

      Just as a reminder, the above statements are only true with static pressure.

        I think breid wins. Does everyone want to be right, or almost right?

        Breid, will the capillary action/meniscus vary as to the pipe material?

          good question. not as far as i know. been a long time since i studied any of this. i would say not as ca is directly proportional to the diameter. but that doesn't mean that there are not other things at play, that i don't remember. i left college in 1965. as for meniscus, well if you were to change the properties of the straw who knows. i want to say that in physics class we cut off a straw and made it shorter than the glass. then set there with an eye dropper and keep adding drops until we got the straw to have a convex meniscus. the water was "crowned" above the straw. i'm NOT in college anymore, so you are on your own. breid.................

            ...the water was "crowned" above the straw. ...
            This I believe is due to surface tension/molecular attraction of the water. Impurities in the water and other factors can influence its behavior.
