The Knudsen paradox refers to a phenomenon in the field of gas dynamics, particularly in the context of kinetic theory of gases. It arises when discussing the behavior of gas molecules in a low-density environment, where the mean free path (the average distance traveled between collisions) is comparable to or larger than the dimensions of the system.
