This paper investigates the influence of non-equilibrium evaporation on the properties of the critical flow of vapour-liquid mixture. As the non-equilibrium vapour generation is assumed to be dominant in a vapour-liquid flow, the Homogeneous Relaxation Model (HRM), with non-equilibrium mass transition, is selected and reduced to the equation for the linear pressure waves. Basing on this equation, the evolution of linear pressure wave in the non-equilibrium, two-phase mixture has been calculated. The conclusions coming from this calculations created a background for the concept of the pseudo-critical flow. A short description of the pseudo-critical flow regime is given and the main difference between the critical flow of equilibrium and non-equilibrium fluid are discussed. Finally, the remarks concerning a kind of relativity of the critical flow for non-equilibrium fluids are given.
