Abstract: An expression is derived for the maximum admissible increment of entropy in a steady gas flow in a variable-section channel with energy supply and with dissipation of kinetic energy. A condition of the transition through the velocity of sound is obtained for a quasi-one-dimensional flow. Examples of flows are considered.

Keywords: channel, energy supply, dissipation, entropy maximum, transition through the velocity of sound, pseudoshock.
