A stream line is___________________?
Correct answer: A. Fixed in space in steady flow
- A. Fixed in space in steady flow
- B. Always the path of particle
- C. Drawn normal to the velocity vector at every point
- D. A line connecting the mid points of flow cross-section
Explanation
In steady flow, the velocity field does not change with time, so streamlines remain fixed in space. A streamline is tangent to the velocity vector, not normal to it.

The more specific you are, the faster it gets fixed. A source beats an opinion.
