Abstract: We derive the constitutive equations of causal relativistic dissipativehydrodynamics $d$-hydrodynamics from perfect nonextensive hydrodynamics$q$-hydrodynamics using the nonextensive-dissipative correspondence NexDCproposed by us recently. The $q$-hydrodynamics can be thus regarded as apossible model for the $d$-hydrodynamics facilitating its application to highenergy multiparticle production processes. As an example we have shown thatapplying the NexDC to the perfect 1+1 $q$-hydrodynamics, one obtains a propertime evolution of the bulk pressure and the Reynolds number.
