Abstract The normal fluid density ρ n and the specific heatc v are calculated for helium II flowing through plane parallel slits and capillaries with a square profile at temperatures below1 K. Both functions increase over their bulk values if the thermal phonon wavelength λ becomes comparable to or larger than the smallest dimensiond of the container. The asymptotic expansions which are obtained in this paper have an overlapping range of validity, and therefore describe ρ n andc v rather accurately for all values of λ/d.
