Abstract
The considerations of a previous publication on the same subject, based on the two-fluid model, are generalized to the case that the relaxation time for the transformation of the two fluids into each other may not be regarded as infinitely small and that pressure has a noticeable influence on their equilibrium ratio. It is shown that under these circumstances a damping of first sound results in addition to that due to viscosity. From the experimentally determined attenuation it follows that the relaxation time near the γ-point must be either less than about 10−12 s or greater than about 10−4 s. The theory of the temperature jump at a material boundary for stationary heat flow is discussed on the same basis.
