Nitrogen vs Oxygen Permeation PDF

A document that provides a detailed explanation of nitrogen and oxygen permeation in relation to Graham's Law. It discusses the differences between effusion and permeation, emphasizing molecular size and kinetics rather than weight as the critical factors. The document also covers experimental findings on the permeation rates of O2 and N2 through rubber, noting that oxygen permeates faster than nitrogen due to its smaller effective molecular size. Practical implications for tire inflation, particularly with enriched nitrogen, are highlighted to reduce maintenance and improve performance.
