10/30   I want to calculate gas flow impedances through a tube at a few
        PSIG.  can someone recomend a reference on the web that will
        help with this?
        \_ The proper term is called "pressure drop."  If you insist,
           go to library and look for Perry's Handbook. Otherwise,
           go bug some Chemical Engineering or Mechanical Engineering
           nerds for help.  I am sure you have helped them answering
           UNIX questions in the past. It's just returning favor.
           \_ thanks.  i didn't know what it was called by CE people.
              google doesn't help much if you don't know the right
              buzzwords.  in case anyone cares, here's the table
              i was trying to find:
              http://www.copper.org/tubehdbk/tables/table4.html
              -op
        \_ gee i'm sure motd is a better place to ask than google, this
           isn't incredibly esoteric or anything, and i'm sure there's
           an expert in fluid dynamics here and that google doesn't have
           anything that could help you.
           \_ ie, STFW
           \_ 1) Cal is a top-rate engineering/science school
              2) Many Cal engineers/scientists are CSUA members
              3) When searching for information, it often helps to also
                 ask at a place where you know there may be some top-rate
                 {whatevers} in their field to help you.  The motd is one
                 possible place for this.  What is so fucking difficult about
                 this that makes you no-life no-clue pack of twats feel you
                 have to make up for your lack of knowledge and willingness to
                 help with not-particularly-clever snide putdowns?  You are
                 LAME.  Let me read it to you, L.A.M.E.  You wear the flaming
                 hot neon pink capitalized letter 'L' tattoo on your pimply
                 forehead.  You will NOT reproduce, as you are a jaffa
                 fuckwit.  Your family tree does not fork.  You smell bad.
                 Dogs and small children run at the sight of you.  Disease
                 and stupidity pool wherever you place your stumbling hairy
                 feet.  Let me also not forget that you haven't the brains
                 god gave coleslaw.  Your mother wears combat boots.  You
                 fly DDs.  Your job description includes the term
                 "pencilneck".  You chew your toenails.  You have an
                 average feeling about this level.  You are flatulent. People
                 avoid things you have touched.  I fart in your general
                 direction.  You have all the cans in a six pack but lack
                 the plastic thingy to hold it all together.  L A M E.  There
                 is no excuse for you, you shit-festering son of a one-
                 balled male prostitute.  The ten-foot poles in your vicinity
                 have all been removed, as no one uses them anyway.  You are
                 a one-handed typer.  Your credit card statement shows
                 subscriptions to bukkake sites.  Do us all a favor;  go sit
                 in a corner and continue to fester and rot as you have been
                 doing all along, but from now on, do so quietly.   -John
                 \_ yes, yes righteous indignation blah blah sancitmonious
                    blither blah blah you suck.  you think about this
                    entirely too much.
                        \_ Not really...I think I had a point, but then I just
                           felt like insulting you a lot.  -John
                           \_ you had a point.  absurdly obscure technical
                              questions sometimes get answered on the motd.
                              in the end, i only found what i was looking
                              for because of motd help. the motd alone
                              did not solve my problem, but google + motd
                              did. -op
                 \_ Rock on brother!
