If velocity of all fluid particles is same all the time then it is called

  • A.Viscous force
  • B.Critical velocity
  • C.Streamline flow
  • D.Terminal velocity

Answer: C

This is streamline, or laminar, flow.

Every particle passing a given point follows the same path with the same velocity, so the streamlines never cross. Above a critical speed the flow becomes turbulent and the motion at each point varies irregularly with time.
