Question

what is stream line flow in fluid mechanics

Answer 1

They differ only when the flowchanges with time, that is, when the flow is not steady. Considering a velocity vector field in three-dimensional space in the framework of continuum mechanics, we have that: Streamlines are a family of curves that are instantaneously tangent to the velocity vector of the flow

Answer 2

$\huge\textbf{Stream line flow :}$

The flow in which every particle of the liquid follows exactly the same path of it's preceding particle with same flow and has same velocity as that of preceding particle while crossing that point.


$\textbf{Properties :}$

→ No, two stream lines can't cross each other.

→ The greater is the crowding of stream lines at a place the greater is velocity of liquid particles.
