Correction Temperature and Volume Dependence of the Viscosity of Water and Heavy Water at Low Temperatures. Kenneth R. Harris* and Lawrence A. Woolf, J. Chem. Eng. Data 2004, 49, 1064-1069. There are two errors to be corrected in this paper. These relate to the densities used in the calculations of viscosities from the experimental fall times. The first was due to a mistake in transferring density and molar volume data for ordinary water to the final version of Table 2 at temperatures of 278, 283, and 298 K. The values published were derived from the older IAPWS correlation of 1985.16 The correct values are derived from the formulation of 1995,17 for which we employed the NIST/ ASME Steam Properties Database Software, version 2.2. This affects some of the reported viscosities very slightly
(in the fourth decimal place), and corrected values for both density and viscosity are given below. The values given in Tables 4 and 5 for the coefficients of best fit to eq 4 for ordinary water were based on the correct densities and are therefore unaffected, as are the Figures. The other is an incorrect attribution on p 1067 for the equation of state used for D2O. The citation should be for the work of Aleksandrov and Matveev (ref 20), not ref 16. The equation of state in the latter paper is valid only below 100 MPa. Acknowledgment We thank Dr Marcia Huber (NIST, Boulder, CO) for detecting the error in Table 2.
