In reply to the discussion: Another 'DeflateGate' theory. Weather/temperature? [View all]Faryn Balyncd
(5,125 posts)32. It might depend on the internal temperature of the balls before inpection. The temperature drop from
... normal locker-room temperature would appear to cause less than 1 PSI drop by the time they equilibrated to outside temperature, perhaps none if the balls were outside for a period before inspection.
But if the balls were "conditioned/warmed-up" so that internal air temperature was in the 90's, then inspected 2 hours before the game before they cooled down, there could be enough drop in pressure by the time it equilibrated to 51 degrees to drop pressure from 12.5 to 10.5 PSI by the calculations in the OP's article.
We don't know what the pressures were for the 10 balls, other than that they were under 12.5 PSI, though not as low as the one at 10.5.
See a possible ball "conditioning" protocol that could perhaps give such numbers in Reply #25.

Accuweather says based on the temp change the FB's would have deflated by .4 psi not 2 psi

so balls on one side of field deflate, and those on the other side do not? magic not science
