In a demonstration of the qualities of liquid Helium in type 1, and type 2 the fact that a super-fluid can permeate through capillaries which are too small for type 1 Helium to pass through.
I was wondering about the equation which determines the capillary radius threshold under which the porous barrier is no longer permeable. Doesn't it also depend on the surface tension?
