Half right, the pressure changes thereby affecting the mass of air induced.

When I stated 'actual volume flow' that was in reference to the mass of air at atmospheric pressure, but from now on I will talk about it as mass only.

So can someone confirm or disprove that as vacuum trends to 0.Hg, air mass increases? That equation on the Eng Tool Box suggests otherwise....
