Abstract

From the Langer and Fisher thermal-fluctuation theory we have determined the pressure-velocity dependence for pressure-driven intrinsic superfluid helium flow to be

p \propto \exp (\frac{- β ρ_{s}}{ρ v_{s} kT})

. Experiments of pressure-driven intrinsic flow through submicron pores in porous mica are in agreement with this relation.
