Streamlines are space curves drawn tangential to the velocity vector at all points in the flow field at any instant of time. Geometrically, they represent Eulerian approach for flow velocity description.
They cannot intersect each other.
Streak line is the locus of the temporary location of all particles that have passed through a fixed point in the flow field
