Question

Along a streamline, 

विकल्प

• the velocity of a fluid particle remains constant.

• the velocity of all fluid particles crossing a given position is constant.

• the velocity of all fluid particles at a given instant is constant.  

• the speed of fluid particles remains constant.

Answer 1

the velocity of all fluid particles crossing a given position is constant.

Explanation:

Each particle's velocity at a specific cross-section is constant for a streamlined flow.
