Shear Viscosity of 3-Methylpentane—Nitroethane near the Critical Point

Abstract

Shear viscosity coefficients for a mixture of 3-methylpentane—nitroethane of critical composition were determined over the temperature range 6×10−6≤ ε ≤ 2×10−2 by an improved capillary viscometer. The data were analyzed by alternate procedures both of which give strong support to the view that the viscosity singularity is indeed very weak over a wide temperature range.
