THE hydrodynamic properties of liquid helium-II present a complex picture. In thermally induced flow the superfluid exhibits a well defined critical velocity above which non-linear frictional forces appear. 1 These have been explained in terms of turbulence in the superfluid. In isothermal flow the
It is demonstrated that a simple, "'one-dimensional'" balance equation for the superfluid vorticity can already account for the occurrence of the wmous types of nonuniform distributions of superfluid turbulence observed in capillary flow of helium I1. Expressions for the rates of creation and annihi
