We use numerical simulations to examine the mass-velocity, m(v), and intensity-velocity, I(v), relations in jet-driven molecular outflows up to an age of 2300 yr. We find that the m(v) relation is a power-law, , the exponent of which increases with time up to at yr. It then becomes roughly constant. This indicates that does not evolve throughout the lifetime of a molecular outflow, at least in the context of the jet-driven model.
