It wouldn't be accurate (you'd still have displacement), but the dispacement of the air pushing the ball up could be assumed to be the same in both cases if the ball is the same volume either way.<br /><br />If the ball isn't the same volume either way (which I suppose is the reason you'd under-inflate), then you could weigh it in a vacuum (assuming the ball survived the vacuum) or a partial vacuum - enough to get the two balls to occupy the same volume. Orrr, you could remove the air from the ball and figure out how much there was there. But the best thing to do would be just stick a pressure gauge in there.Erichttps://www.blogger.com/profile/15948916344890835415noreply@blogger.comtag:blogger.com,1999:blog-4912713243046142041.post-47262132212915095922015-01-20T11:47:52.589-06:002015-01-20T11:47:52.589-06:00Ballparking using the ideal gas law (assuming T=30...Ballparking using the ideal gas law (assuming T=300K and the filling gas being nitrogen) got me a difference between a 13psi ball and a 10psi ball at .017oz, and between 13psi and 8psi (no idea what an underinflated football is likely to clock in at) at .029oz.

If the ball's volume doesn't change, then in theory it would weigh more. In practice, it would seem to be very difficult to detect such a small weight difference. But of course maybe what they did was both weigh and check the pressure, as a standard thing, which was perhaps misreported in the press.Anonymousnoreply@blogger.com
