Flow of Liquid Helium II

J. F. ALLEN &  A. D. MISENER

A SURVEY of the various properties of liquid helium II has prompted us to investigate its viscosity more carefully. One of us1 had previously deduced an upper limit of 10−5 C.G.S. units for the viscosity of helium II by measuring the damping of an oscillating cylinder. We had reached the same conclusion as Kapitza in the letter above ; namely, that due to the high Reynolds number involved, the measurements probably represent non-laminar flow.
