Question

A streamline is defined as the line

• A. Parallel to central axis flow
• B. Parallel to outer surface to pipe
• C. Of equal velocity in a flow
• D. Along with the pressure drop is uniform

Answer 1

Answer:

C. Of equal velocity in a flow

A streamline is an imaginary line in a fluid, the tangent which gives the direction of the flow velocity at that position. In other words, it's a line that is everywhere tangent to the velocity vector. It shows the pathway a fluid element will follow in a steady flow. So, the correct answer is option 3
