Abstract
The idea of a unified model for all astrophysical jets has been considered for quite some time. We present here a few scaling laws relevant to all type of astrophysical jets, analogous to those of \citet{sams96} which are widely used for astrophysical black holes. We use Buckingham's $ \Pi $ theorem of dimensional analysis to obtain a family of dimensional relations among the physical quantities associated to astrophysical jets.
