By using the same co-axial cylinder cell as in the previous report, measurement of thermal conductivity of water and steam is carried out in the temperature range from 104 to 420°C and in the pressure range from 98 to 1470 bar. The accuracy of the results is estimated to be better than 1.7% below 400°C and of the order of 2-2.5% above 400°C. The results are well expressed by a simple equation of temperature and density. A comparison with the published data up to now show that the present results agree well with the other data in the lower pressure region than 500 bar. A higher pressures than 1000 bar, the discrepancy between the data by Amirkhanov-Adamov and those of the present work is very large both in the water and steam region, and a large uncertainty of the former is suspected.
