We solve second order relativistic hydrodynamics equations for a boost-invariant 1+1dimensional expanding fluid with an equation of state taken from lattice calculations of the thermodynamics of strongly coupled quark-gluon plasma. We investigate the dependence of the energy density as a function of proper time on the values of the shear viscosity η, the bulk viscosity ζ , and second order coefficients, confirming that large changes in the values of the latter have negligible effects.
