Solutions of the basic polytropic flow equations appropriate to the physical conditions of extragalactic jets well outside the acceleration region within their parent active galactic nuclei are presented. The solutions are based on observationally determined galactic mass distributions and quasi-periodic brightness enhancements along the jets. It is demonstrated that such a model is able to connect the observed morphology of jets to processes (including shocks or density condensations) which can give rise to the brightness enhancements, as well as to provide estimates for the jet flow speeds which are consistent with values implied by observations.
