Perry's Handbook Viscosity May 2026

Unlike liquids, gas viscosity with temperature. Perry’s frequently cites Sutherland's Formula for these predictions:

For wide-range calculations, Perry’s uses empirical correlation equations. Perry's Handbook Viscosity

Thousands of organic and inorganic compounds are listed with experimental viscosity values at specific temperatures. Unlike liquids, gas viscosity with temperature

μ=μ0(0.555T0+C0.555T+C)(TT0)1.5mu equals mu sub 0 open paren the fraction with numerator 0.555 cap T sub 0 plus cap C and denominator 0.555 cap T plus cap C end-fraction close paren open paren the fraction with numerator cap T and denominator cap T sub 0 end-fraction close paren to the 1.5 power : Viscosity at temperature (Rankine). : Sutherland's constant for the specific gas.

While simple fluids use standard definitions , Perry’s relies on specific models for temperature dependence: For Liquids

Quick-reference charts where you draw a line between temperature and a substance point to read the viscosity. The Go-To Equations
