  Hey, what's the grams/mole of the 1% Argon?  (-:

   Sorry my education ain't good enough to follow all the grams/mole stuff
  but the bottom line caught my eye:

  So 325 grams per second only equals 1CFM??
 
  Doesn't that make a cubic foot of air weigh about 43 pounds????!

  Hey, I remember Bernoulli..  He got all those gas laws passed so He
 could invent the carburetor, right??
  Just think how different gas physics would be if He'd 
 invented EFI first... (-;

 Happy motoring,
