prissythecat Posted January 26, 2015 Posted January 26, 2015 Compressed air comes out of the nozzle extremely cold(due to technical math/science reasons). Even heated air would be reduced in temperature enough when focused through a small point to not effect the end result. Simple science experiment.....blow air onto your hand with an open mouth.....then do it through purced lips. The open mouth blowing is significantly warmer than purced lips. The narrower the hole, the colder the temperature. You must have received an F in Science?
devldog131 Posted January 26, 2015 Posted January 26, 2015 The company that makes the balls came out and said the only way for a ball to deflate that much in that amount of time is a pump needle. Case closed. Does anybody have a link on this? I live in MA and would love to throw it in the faces of the patriots* fans I deal with on a constant basis.
TheBillsWillRiseAgain Posted January 26, 2015 Posted January 26, 2015 This article quotes a couple representatives for Wilson Sporting Goods. http://www.boston.com/sports/columnists/wilbur/2015/01/thats_bs_-_wilson_doesnt_seem_to_buy_belichicks_sc.html
BRH Posted January 26, 2015 Posted January 26, 2015 It appears that a team from Carnegie Mellon found out that this sort of deflation could happen. http://profootballtalk.nbcsports.com/2015/01/25/bill-nye-says-bill-belichick-made-no-sense/ And they were unable to explain why the Colts' balls did not also similarly deflate.
K D Posted January 26, 2015 Posted January 26, 2015 how vigorously is Tom Brady rubbing his balls before the game? Belicheat said their tests show that "roughing up" the footballs cause them to inflate 1 psi? i find that hard to believe. not to mention you idiots were 2 psi under so i don't understand their argument. the NFL is dragging their feet because they don't want to interfere with their precious Super Bowl. i am hoping for a severe punishment. not just because the balls were deflated, but due to the fact that a) they lied about it and b) they have been caught cheating before. 1 yr suspension for Belicheat
Dibs Posted January 26, 2015 Posted January 26, 2015 (edited) You must have received an F in Science? No, I got an A. http://en.wikipedia.org/wiki/Joule%E2%80%93Thomson_effect the Joule–Thomson effect (also known as the Joule–Kelvin effect, Kelvin–Joule effect, or Joule–Thomson expansion) describes the temperature change of a gas or liquid when it is forced through a valve...... The method of expansion discussed in this article, in which a gas or liquid at pressure P1flows into a region of lower pressure P2 via a valve or porous plug under steady state conditions and without change in kinetic energy, is called the Joule–Thomson process. The region of lower pressure in this case is the football. what? the air feels is cooler because it expands as it comes out the nozzle, and subsequently cools. Think air conditioning. Pretty much right. The air expands into the football......and reduces in temperature as it does so. Edited January 26, 2015 by Dibs

Joule-Thomson effect is not really going to apply to the inflation of a football. Btw, if you are thinking about the cold air coming out of one of those air dusters, the air is cold due to vaporization of the liquid in the can. Its not cold because of Joule-Thomson .
TheBillsWillRiseAgain Posted January 26, 2015 Posted January 26, 2015 So far the arguments are:1. The weather/atmosphere did it. The manufacturer of the football gave a statement saying there was no way for that much air to leave the football without putting it in a freezer or using a pump needle to remove it. 2. Tom Brady likes the ball at the minimum levels and Luck likes them at the max levels, so they both lost air but the Colts' balls were still in the allowed range because of a higher starting pressure. If true, Tom Brady certainly wouldn't be the only QB in the league to like the balls filled to the minimum levels, and he's definitely not the only QB to play games in cold weather. Are you trying to tell me that nobody ever noticed the balls being under the acceptable range in any of the cold weather games of the past few seasons? 3. The deflation was caused by the cold weather that particular day Then why did it also happen in the November Colts/Patriots game? And the Patriots/Ravens game? We have teams complaining on at least 3 separate occasions that the Patriots' balls were under inflated. We have statistics that show the Patriots fumbling(or rather not fumbling) at a highly abnormal rate compared to the rest of the league over the past 4 years We have statistics that show Brady's yards-per-attempt have been abnormal compared to other QBs for the past 4 years We have the fact that the Patriots were caught outright cheating in 2007 and punished by the league We have a Head Coach saying he's never heard of or talked about ball pressure with anyone in his career We have a 17th year QB claiming he's never once squeezed a football to check the air pressure Seems pretty obvious to me.
BillsFan-4-Ever Posted January 26, 2015 Posted January 26, 2015 (edited) Bellyache claimed he knew nothing about footballs..... or how Tom likes them handled. Has he been speaking of them since the PC? Edited January 26, 2015 by BillsFan-4-Ever
bobobonators Posted January 26, 2015 Posted January 26, 2015 I hate the pats but dont u guys ever get tired of this topic? What was the score at halftime during deflate gate and what was the final score after the balls were all properly inflated. I get something was prob done to the balls but the pats actually played better with the properly inflated balls.
BillsFan-4-Ever Posted January 26, 2015 Posted January 26, 2015 (edited) nope. I'd ask similar...... Don't the EJ detractors ever get tired of the topic? as to the 2nd half.... in playoffs that's when teams usually pull away leaving the opponent in the dust. The Colts were out manned, they are back into the same old get a VG QB and let the rest of the team go lacking Edited January 26, 2015 by BillsFan-4-Ever

Btw, if you are thinking about the cold air coming out of one of those air dusters, the air is cold due to vaporization of the liquid in the can. Its not cold because of Joule-Thomson . You are correct - mostly. Air does cool when it expands. If you have a high pressure line and a gas is released it will cool, in some cases drastically. This type of system is used in many applications from swamp coolers in desert homes to cooling of IR systems in Military applications. The total pressure drop is what is important and how rapidly the pressure is released. When you are inflating the ball it is not expanding into the ball, it is being compressed. If you are inflating the ball to 13.5 PSI you only need a little more than this to move the air into the ball - not enough pressure drop to cause a temperature change in my opinion. You could design a simple machine to heat the air and manually pump it into the ball. Who knows what happened.. probably the Pats ball boy just let a little air out of the ball and got mixed up and forgot about ball #12. Fun to talk about tho.. I can't get enough of it

But im just saying this entire ball deflation debate probably had little impact on the game. The patriots were just worlds better than the colts and a few psi wouldnt have made a difference.
CodeMonkey Posted January 27, 2015 Posted January 27, 2015 And they were unable to explain why the Colts' balls did not also similarly deflate. I've never seen anything that states as a fact that the colts footballs were tested, is there anything definitive?

What I see here is a bunch of Bills fans having a bit of fun trashing their despised rivals.
