In the present paper, we prove convergence rates for the Local Discontinuous Galerkin (LDG) approximation, proposed in Part I of the paper, for systems of p-Navier-Stokes type and p-Stokes type with p∈ (2,∞). The convergence rates are optimal for linear ansatz functions. The results are supported by numerical experiments.
