Helium Research Center internal report viscosity of the helium-nitrogen system from 133℗ʻ to 740℗ʻ K for pressures between 1 and 240 atmospheres

"This report presents a method for the prediction of the viscosities of gaseous helium, nitrogen, and helium-nitrogen mixtures over the practical range of pressures, temperatures, and gas compositions encountered in Bureau of Mines helium purification processes and in the gas reservoir where crude helium is being stored for future use"--Leaf 7.
