Along a streamline a) the velocity of a fluid particle remains constant b) the velocity of all fluid particles crossing a given position is constant c) the velocity of all fluid particles at a given instant is constant d) the speed of a fluid particle remains constant
Correct option is C) Along a streamline, Av=constant. This means that at a particular cross-section, the velocity of all fluid particles is constant. Hence, we can say that the velocity of all fluid particles crossing a given position is constant.
