The 1996 corvette GM 12v electric motor driven air pump I have weighs just
2 lbs, 4 oz. I have no idea what amount of air it will supply yet.

Paul Lamar teased:

Fill a balloon and weigh it before and after :-)
Anybody care to do the math on the results?

Very funny Paul.  Without knowing the "strength" of the balloon, or at least
the pressure of the air within, one cannot determine the amount of air the
pump will supply.

BTW, since your considering this pump for vacuum power instruments, wouldn't
it be better to measure the amount of air it consumes (generating vacuum)
rather the amount of air is supplies?  :-)

If you carefully weigh the balloon before and after, measure the temp of the
air before and after and measure the size of the balloon when full you
should be able to calculate the additional volume (corrected to ambient 
pressure) of air in the balloon taking into consideration its buoyancy.
