  We express the transport coefficients appearing in the second-order evolution
equations for bulk viscous pressure and shear stress tensor using
Bose-Einstein, Boltzmann, and Fermi-Dirac statistics for the equilibrium
distribution function and Grad's 14-moment approximation as well as the method
of Chapman-Enskog expansion for the non-equilibrium part. Specializing to the
case of transversally homogeneous and boost-invariant longitudinal expansion of
the viscous medium, we compare the results obtained using the above methods
with those obtained from the exact solution of the massive 0+1d relativistic
Boltzmann equation in the relaxation-time approximation. We show that compared
to the 14-moment approximation, the hydrodynamic transport coefficients
obtained by employing the Chapman-Enskog method leads to better agreement with
the exact solution of the relativistic Boltzmann equation.
