Two alternative evolution equations for the vortex line density L in counterflowsuperfluid turbulence in 4He were proposed by Vinen in 1958. Theseequations was recently generalized to counterflow superfluid turbulence inrotating containers. Here, according with the formalism of Non-EquilibriumThermodynamics, the compatibility between the alternative Vinen equationas evolution equation for the vortex line density in rotating counterflow turbulenceand the velocity of the superfluid component is studied. From thecompatibility request a new term dependent on the anisotropy of the tanglearises.
