The viscosity of five gaseous hydrocarbons

Abstract
The paper presents new data on the viscosity of CH4, C2H4, C2H6, C3H8, and C4H10 at atmospheric pressure and in the temperature range 25–200°C. The measurements were absolute and were performed in an oscillating‐disk instrument. The results fit into the extended law of corresponding states of Kestin, Ro, and Wakeham. The scaling constants σ and ε for each gas which assure such a fit are calculated in the paper.
