I've got 2 electric pumps for filling air mattresses. I'm looking for a
way to determine which one will fill an air mattress quicker - other
than actually filling the same air mattress with each pump. That's boring!
This is more of a fun project than anything else. What do we all have
lying around the house or shop that we could use to rig up a air flow
meter or other means of testing the pumps to see which one puts out the
most air using the same sized nozzle.
One pump has a larger output port than the other, so the first thing I
assume I should do is use the same nozzle that would be used for a given
air mattress since back pressure could alter the performance.
After that, I'm looking for suggestions. Things like...
Push a column of water up a tube.
Use a water pressure meter at the end of a garden hose filled with water
and sealed so the pump would put pressure on it.
Blow a pile of wood chips out of a tube and measure the distance thrown.
