The magnitude of B2T2, proportional to momentum-conserving (MC) electron–electron collisions is compared to ρimp + A2T2 + A5T5, which is proportional to momentum-relaxing (MR) collisions by electrons and phonons and ρ0, which is a measure of boundary scattering. In a limited temperature window (7 < T < 13 K), the hierarchy for hydrodynamic regime is satisfied
