It has recently been suggested 1,2 that liquid helium II shows a certain similarity with a Knudsen gas, the atoms moving with a very long mean free path. From the formula which is quite general ( l is mean free path, χ is thermal conductivity, c ν is specific heat per gram, Ï is density, ν is vel...
