Viscosity, Stokes' Law and Reynolds Number

Which of the following statements is correct about streamline flow?

In streamline flow, fluid particles follow fixed paths (streamlines) with constant velocity at each point, occurring at low speeds where viscous forces dominate, not requiring high speed or turbulence. As per NCERT, applying relevant law/formula with correct units and sign convention leads to Particles follow fixed paths. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.

Viscosity, Stokes' Law and Reynolds Number

What is the primary condition for streamline flow to occur in a fluid?

Streamline flow occurs when viscous forces dominate inertial forces, keeping fluid motion steady and layered. This requires a low velocity, below the critical speed where turbulence begins. As per NCERT, applying relevant law/formula with correct units and sign convention leads to Low velocity. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
