Here's a way, perhaps, that the relativistic Euler equation article could be revised:

= Relativistic Euler equations = In fluid mechanics and astrophysics, the relativistic Euler equations are a generalization of the Euler equations that account for the effects of general relativity.

Derivation
The relativistic Euler equations are derived from the continuity equation of the stress-energy tensor,

$$\nabla_\mu T^{\mu\nu}=0,$$

where $$T^{\mu\nu}$$ is the stress-energy tensor and $$\nabla_\mu$$ is the covariant derivative.
