Some helium is supplied from liquefaction of air on a large scale. From a calibration performed at room temperature in hydrogen and helium we found. C was determined by means of a calibration at a temperature at which the viscosity is accurately known. As a function of temperature in kelvins the viscosity can be estimated using the semi empirical vogel fulcher tammann equation.

Density specific heats viscosity and thermal conductivity at pressures from 1 to 100 bar and from room temperature to about 1800 k. Adsorption of other gases on cooled activated charcoal yields 99 995 percent pure helium. Compressibility factor for helium data sheet 11 001 in a compendium of the properties of materials at low temperature pnese 11 by the national bureau of standards cryogenic engineering laboratory r. In accordance with measurements previously made by one of us together with w.

Absolute dynamic and kinematic viscosity dynamic absolute and kinematic viscosities convert between centistokes cst centipoises. At liquid oxygen temperatures after measurements performed on the same gases 3 80. The amount of helium obtainable from 1 000 tons 900 metric tons of air is about 112 cubic feet 3 17 cubic metres as measured at room temperature and at normal atmospheric pressure. Density specific heats viscosity and thermal conductivity at pressures from 1 to 100 bar and from room temperature to about 1800 k petersen h.

N2 an estimation of the properties of helium is carried out on the basis of a literature survey.
