A new formulation is presented of the static relative permittivity or dielectric constant of water and steam, including supercooled and supercritical states. The range is from 238 K to 873 K, at pressures up to 1200 MPa. The formulation is based on the ITS-90 temperature scale. It correlates a selected set of data from a recently published collection of all experimental data. The set includes new data in the liquid water and the steam regions that have not been part of earlier correlations. The… 

Reference Correlations for Thermophysical Properties of Liquid Water at 0.1 MPa

Simple but highly accurate correlations have been developed for the thermodynamic properties (including density, heat capacity, and speed of sound), viscosity, thermal conductivity, and static

Determination of the Relative Permittivity, εr, of Heptane at Temperatures between (303 and 363) K and Pressures below 60 MPa with a Concentric Cylinder Capacitor at a Frequency of 1 kHz

The relative electric permittivity, er(T, p), of liquid heptane has been determined with an estimated relative expanded uncertainty of ± 0.018 % from measurements of the complex capacitance of a

Hydrothermal properties of the COS/D2 water model: a polarizable charge-on-spring water model, at elevated temperatures and pressures

Molecular simulations have been conducted to assess the pVT properties and static permittivity of the charge-on-spring polarizable water model COS/D2 at hydrothermal conditions from 300 to 450 °C and

A formulation for the relative permittivity of water and steam to high temperatures and pressures evolved using genetic programming

This research represents a successful application of artificial evolutionary techniques to relative permittivity prediction in physical chemistry.
