Thermal Conductivity of Water at High Pressures

Abstract

The thermal conductivity of water has been measured between 30° and 140°C at pressures ranging up to 8000 kg/cm² using Bridgman's concentric cylinder technique. At atmospheric pressure, the values obtained are about 1% less than the most probable values estimated by Powell. At higher pressures, the values agree well with Bridgman's measurements where the data overlap. The results are discussed in terms of Hall's two fluid model of water.
