Edit: I see the tester used an anemometer, which measures just the air moving THROUGH the anemometer.
If the exhaust is smaller than the intake, then air will move at a higher speed through the exhaust. Thus the anemometer will show a higher reading.
- lupire 4y agoIt has to come from somewhere, by conservation of mass.
- danuker 4y agoIndeed. I was thinking it's from some other holes of a non-airtight case. But actually, the mass conservation happens through air around the anemometer (i.e. air not getting measured, but still moving).
