NDA 2016 Physics question

Along a streamline flow of fluid

(A)the velocity of all fluid particles at a given instant is constant
(B)the speed of a fluid particle remains constant
(C)the velocity of all fluid particles crossing a given position is constantCorrect
(D)the velocity of a fluid particle remains constant

Answer: (C)

Solution

In streamline (steady) flow the velocity at any given point does not change with time: every particle that passes through a point has the same velocity as the particles that passed through it before. The velocity may be
