mean direction of a number of particles at the same instant of time

trace made by a single particle over a period of time

instantaneous picture of positions of all particles in the flow which passed a given point

the line of flow, normal to which at any point gives the velocity vector

steady flow

uniform flow

laminar flow

irrotational flow

Streamlines cannot start or end anywhere except at the interface or infinity.

Streamline spacing varies directly as the flow velocity.

Streamlines can met at a stagnation point where the velocity is zero.

The flow is only along the streamline and not across it.

radial flow

spiral flow

free vortex flow

force vortex flow
