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 valocity of all fluid particles at a given instant is constant

D

the speed of a fluid particle remains constant

Text Solution

Verified by Experts

The correct Answer is:
B
As we know for a streamline flow of a liquid velocity of each particle at a particular cros-section is constant, because Av=constant (law of continuity) between two cross-section of a tube of flow.
