• An equation for the thermal conductivity of water and steam is formulated in the temperature range from 0 to 800℃ and in the pressure range from the triple point pressure to 1000 bar, including the critical region. For the formulation 43 references and more than 4000 experimental data are considered and tested for reliability. The agreement of the equation with the experimental data is satisfactory in the whole range of temperatures and pressures including the critical region, and the extent of the uncertainty of the equation is shown in various ranges of temperatures and pressures. The equation is also proved to be applicable to the higher pressure region than 1000 bar with reasonable accuracy.
