Boston, MA (PRWEB) April 29, 2015
Bijan Bowen, a junior at the University of Massachusetts Boston and a Patriots fan, developed Deflate Calc, an application for the iPhone that uses scientific theory to determine estimated PSI based on temperature change. “It was sad that so many people, including celebrity TV scientists didn't have a grasp of freshman high school physics when it came to calculating PSI changes based on temperature” Bowen said, “I developed Deflate Calc so that anyone, even media experts, can quickly enter a starting temperature and PSI, then enter a second temperature and the estimated PSI will be shown."
A consistent issue seemed to be that the Ideal Gas Law, PV=nRT was not being correctly used as people fail to factor in absolute pressure which is not displayed in a standard gauge measurement. A temperature drop from 75 degrees Fahrenheit to 49 degrees Fahrenheit is a drop of 4.7% based in Kelvin temperature. People mistakenly apply a 4.7% drop to the starting PSI of 12.5 to come up with an estimated drop to only 11.9 PSI. They fail to factor in an additional 14.7 PSI for the standard atmospheric pressure for a starting PSI of 27.2 PSI rather than 12.5 PSI. A 4.7% reduction from 27.2 PSI results in 25.9 PSI from which the atmospheric pressure of 14.7 is removed leaving an estimated gauge PSI of 11.2 remaining. Performing these calculations on the fly is difficult and above the skills of most people. A need existed for a quicker way to do these calculations.
Difficulty with the math and science when coupled with preexisting biases leads some people to jump at conclusions wholly unsupported by science.
Now, thanks to Deflate Calc, celebrity scientists, confused ex-player/commentators, game officials and even $1500 an hour investigating attorneys can quickly determine how temperature affects PSI. Deflate Calc is available on the App store for only 99 cents. Bijan Bowen is the developer of apps with tens of thousands of downloads including Bitcoin Guide, Mens Shoe Guide, and Montell, a free speaking communications application, which is a customizable and innovative Augmentative and Alternative Communication (AAC) solution for the iPad to help those who cannot speak but can use the iPad.
