Isentropic Flow

where is the flow velocity, and the potential energy per unit mass. It is clear from Equations (14.25) and (14.32) that the specific entropy is constant along a streamline, but not necessarily the same constant on different streamlines. Such flow is said to be

along a streamline. More generally, isentropic flow is characterized by , , and , constant along streamlines.
