Question

Along a streamline,
A. the velocity of a fluid particle remains constant
B. the velocity of all fluid particle 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 particles remains constant

Answer 1

Correct Answer - B
As we know for a streamline flow of a liquid velocity of each particle at a paricular coss-section is constant, because `Av = constant (law of continuity) between two cross-section of a tube of flow.
