In this paper we incorporate the relativistic equation of state of multi-species fluid in relativistic hydrodynamic code. We show that in the trans-relativistic temperature regime, composition plays a very important role in the temporal evolution of relativistic hydrodynamics. We show this for shock tube tests, as well as, relativistic jets.
