DeuteriumOxide provides thermodynamic property information for deuteriium oxide, otherwise known as heavy water or D2O, which has a molar mass of 20.0275 g/gmol. The thermodynamic properties are determined from the equation of state in:
J. Kestin and J.V. Sengers
New International Formulations for the Thermodynamic Properties of Light and Heavy Water
J. Phys. Chem. Ref. Data, 15(1):305-321, 1986.
The correlation is valid for temperatures in the range between the triple point (276.97 K) to 800 K at pressures up to 100 MPa.
Specific internal energy and specific entropy values are referenced to 0 kJ/kg and 0 kJ/kg-K, respectively, for saturated liquid at 276.935 K.
Viscosity and thermal conductivity information is from:
N. Matsunaga and A. Nagashima
Transport Properties of Liquid and Gaseous D2O over a Wide Range of Temperature and Pressure
J. Phys. Chem. Ref. Data, Vol. 12, No.4, 1983.
The sublimation pressure curve (valid for temperatures between 70 K and 276.969) and the melting pressure curve for ice form 1h are determined from:
Stefan Herrig, Monika Thol, Allan H. Harvey, and Eric W. Lemmon
A Reference Equation of State for Heavy Water
J. Phys. Chem. Ref. Data 47, 043102 (2018);
Other transport properties are provided using correlations given in:
