The viscosities of water in Na‐montmorillonite systems at various water contents were calculated by different equations using data from experiments conducted by different investigators on: (i) viscous flow of water at different temperatures, (ii) self‐diffusion of water, and (iii) neutron scattering by water. The results were remarkably consistent and showed that the viscosity of the interlayer water is greater than that of bulk water and increases exponentially with decreasing water content. Evidence was also presented to show that the viscosity of this water depends on the b ‐dimension of the associated montmorillonite. By combining the data on viscosity with data on hydraulic conductivity, it was possible to determine the permeability of the montmorillonite at different water contents.
