The shear viscosity of the SPC and SPC/E water models at 277 and 300 K has been determined using equilibrium molecular dynamics. Good agreement with experiment was obtained for the SPC/E model at both temperatures. The viscosity of the SPC model was lower than the experimental value at both temperat

โฆ Synopsis
Constant temperature molecular dynamics (Iv, V, Tensemble) calculations LIZ performed on 216 SPC/E water molecules at temperatures T=298 and 373 K and density 1 g/cm3, using the reaction field method. The calculated values for the static dielectric constant are+,= 70.7kO.8 at T=298 Kande,,=51 kO.35 at T=373 K, whichare in satisfactory agreement with experiment. We have also calculated the temperature dependence of the Kirkwood gx factor. The calculated gx factor decreases with temperature, also in agreement with experiment.

Measurements of the real portion of the dielectric constant of coal-water slurries at 750MHz are reported. Slurries of 40-65wt% of either Illinois No. 6, Utah bituminous or Texas lignite coals over the temperature range 11-71 "C were studied. The dielectric constant was independent of coal type and
