The Dielectric Constant of Supercritical Steam

Abstract
A description is given of the method used to measure the dielectric constant of steam at densities between 0.2 and 0.4 g/cc in the temperature range 377 to 395°C. Smoothed values of the dielectric constant are tabulated at 378, 383, 388, and 393°C for densities from 0.1 to 0.5 g/cc.
