Among physical characteristics of highly collimated flows, the most important feature may be the "Hubble" law linking outflow velocity with distance from the driving source (v ∝ r). The bow shock driven by high-velocity jet may explain this relationship. A set of equations with variable ejecting angles is defined for the outflow shapes, velocity and density structure. The velocity field obtained by numerical method is comparable to the observations.
