Abstract
Thermomolecular pressure ratios of ${\mathrm{He}}^{3}$ have been measured for a tube extending from room temperature to a bulb at 2\ifmmode^\circ\else\textdegree\fi{}K. The results agree within experimental accuracy with ${\mathrm{He}}^{4}$ ratios calculated from the Weber-Schmidt equation. Detailed calculations from this equation are given. Limitations of the equation due to large deviations from ideal viscosity behavior in the liquid helium range are discussed.
