WebStreamlines are a family of curves whose tangent vectors constitute the velocity vector field of the flow. These show the direction in which a massless fluid element will travel at any point in time. [3] Streaklines are the loci of points of all the fluid particles that have passed continuously through a particular spatial point in the past. WebThen the stream function at any point P due to the superposition of a point source of strength Q, a distributed line sink of strength k = Q/a, and a uniform stream of velocity U …
