Abstract
Employing a kinetic framework, we calculate all transport coefficients for relativistic dissipative (second-order) hydrodynamics for arbitrary particle masses in the 14-moment approximation. Taking the nonrelativistic limit, it is shown that the relativistic theory reduces to the Grad equations computed in the “order-of-magnitude” approach.
