Polytrophic Index (n) Calculator

Polytrophic Index (n) Calculator


n is the Polytrophic Index

R is the Universal Gas Constant

λ is the Lapse Rate

g is the Acceleration due to Gravity

Polytrophic index of infinity corresponds to an isothermal atmosphere, stably stratified. Regions in which the lapse rate is inverted have negative values of the Polytrophic Index.
