Book Description
A steady-state hot wire method for measuring the thermal conductivity of light gases in the temperature range 1200 to 2100 K is described. In contrast to other methods, free convection currents and large temperature gradients occur; convection effects are shown to be negligible, and an experimental procedure for eliminating the large gradient effects is described. The thermal conductivity of helium is found to follow the equation deg F. Cores o x 10/sup 6/ = 991 + 0.678(T - 1200) cal/sec cm deg over the temperature range covered. That for hydrogen is deg F. Cores o x 10/sup 6/= 1434 + 1.257(T -12OO) cal/sec cm deg. (auth).

Book Description
Experimental data are given for the dependence of the thermal conductivity on temperature, pressure and composition for three helium-hydrogen mixtures at temperatures from 77.96 to 373.16K and pressures up to 50 mN/sq m. The data were obtained by a routine method in a coaxial cylinder apparatus. (Author).

Book Description
The report represents a systematized and critical survey of the basic experimental data for the most widely studied substances in liquid and gaseous states (for helium, neon, argon, krypton, xenon, hydrogen, nitrogen, oxygen, air, carbon dioxide, ammonia, ten hydrocarbons, carbon tetrachloride, ethyl alcohol and water). Tables of the most reliable values of the thermal conductivity of all the cited substances in a wide range of temperatures and pressures have been compiled. (Author).
