In fluid mechanics, what does the term 'streamline' refer to? (2020)

Step 1: Understand that a fluid is a substance that can flow, like water or air.
Step 2: Recognize that in fluid mechanics, we study how fluids move.
Step 3: Learn that a 'streamline' is a line that shows the direction a fluid particle is moving.
Step 4: Know that a streamline represents the path taken by a fluid particle when the flow is steady, meaning it doesn't change over time.
Step 5: Visualize that if you could follow a tiny particle in the fluid, the path it takes is the streamline.

Streamline – A streamline is a line that is tangent to the velocity vector of the flow at every point, representing the path followed by a fluid particle in steady flow.
