the flow is said to streamline or laminar when every particle
Correct answer: B. moves along the same path as
- A. moves in different direction
- B. moves along the same path as
- C. slowly moves in one direction
- D. none of these
Explanation
Streamline flow (laminar flow): This type of flow is characterized by smooth, parallel layers of fluid particles moving with constant velocity within each layer. The particles don't mix or cross paths with particles in different layers.Moving in different directions (a): This contradicts the definition of streamline flow, where particles within the same layer move in the same direction.Slowly moving in one direction (c): While slowness isn't a defining characteristic of streamline flow, it's true that the velocity of each particle remains constant within a layer. However, the crucial aspect is the parallel movement within each layer.None of these (d): As explained above, option b accurately describes the behavior of particles in streamline flow.

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
