Analysis of transport phenomena with finite speed of perturbations propagation

Known governing equations for transport phenomena predict infinite speed of perturbations propagation. From molecular point of view, infinite speed of perturbations propagation does not seem to be a reasonable physical assumption, because for instance in a gas, any perturbation propagates as a result of molecules collisions. At the same time, governing equations for transport phenomena assuming infinite speed of propagation have been obtained long ago using the molecular-kinetic approach. Such an internal contradiction requires an additional molecular-kinetic analysis whose aim is to answer the following questions:
