Abstract
The viscosity of water in the 19.5–25.5°C temperature range was redetermined by a group of workers at the Norwegian Institute of Technology in 1988, under the stimulus from the IUPAC Subcommittee on Transport Properties headed by Professor J. Kestin. This Note explains an apparent discrepancy, reported in the original work, between the damping-sensitive and the period-sensitive solutions of the working equations employed. The disagreement between the two viscosities reduces to 0.0001 mPa · s, or 0.01 %, when the appropriate corrections to the period are introduced.
