Abstract

Viscosities, obtained with a falling‐cylinder viscometer, are presented for liquid methane, ethane, and propane from their normal boiling points to their critical points and for n‐butane from its normal boiling point to 100°C. The data of this study are compared with those of other investigators.

The experimental viscosities of this study are correlated within ± 5% over the reduced‐temperature range from 0.65 to 0.95 by means of a modified Smith‐Brown correlation. The Grunberg‐Nissan equation for estimating the critical viscosity was tested with the experimentally determined critical viscosities of this study and was found satisfactory.
