I am not really arguing as you are correct about the low quality, however, that is how you measure air volume. Measure the air speed and multiply it by vent area. Hopefully(i doubt it) they included how big the vent was.
Additionally. I am a bit weak on my physics but I think air speed has a direct relationship with evaporating liquids. I would have to see some controlled tests. but hypothesis: given the same volume of air per minute. a higher speed will evaporate water faster, with specific testing on high surface area targets(like hair) for example: them stupid dyson dryers that project a super high speed low area stream of air
