Kinematic viscosities of aqueous mixtures containing poly(ethylene glycol)s (PEGs) with nominal molecular masses ranging from (200 to 10 000) g·mol -1 have been determined at various concentrations and temperatures. The binary experimental data were used to adjust the parameters of a Kumar-like equation. Relative errors around 5.5% were observed between calculated and experimental results. The adjusted parameters also allowed the viscosity prediction for multicomponent mixtures, with an overall deviation of 9.9%.
