Abstract
A method is described for measuring the product of the viscosity and the density of liquid helium by determining the energy dissipation of a piezoelectric cylinder of quartz oscillating in a torsional mode. Data are reported for liquid helium under its own vapor pressure as well as at higher densities.Keywords
