Therefore, the entropy in regions 4 and 4‘ is different. Consequently, the dividing streamline EF between these two regions is a line across which the entropy changes discontinuously. Such a line is defined as a slip line. temperature and density, as well as the entropy and velocity magnitude, are different in regions 4 and 4'.
