    Physical Properties of Heavy-oxygen Water: Absolute Viscosity of H218O between 15 and 35°C
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1972, 68 (11), 1972) Kudish, A. I.; Wolf, D.; Steckel, F.
    The absolute viscosity of highly enriched heavy-oxygen water, H218O, has been measured at 5°C intervals between 15 and 35°C, using a semi-automatic closed viscometer of the suspended-level type. A linear extrapolation was performed to determine the viscosity of 100 % heavy-oxygen water, based upon the measured viscosity of natural water and that of a highly enriched heavy-oxygen water sample. The effect of isotope substitution on the viscosity of natural water has been analyzed for both H218O and D216O. The viscosity ratio at 25°C for H218O/H216O is 1.0536, whereas that for D216O/H216O is 1.2316.
