We consider a mixed finite-volume finite-element method applied to the Navier-Stokes system of equations describing the motion of a compressible, barotropic, viscous fluid. We show convergence as well as error estimates for the family of numerical solutions on condition that: (a) the underlying physical domain as well as the data are smooth, (b) the time step math formula and the parameter math formula of the spatial discretization are proportional, math formula, and (c) the family of numerical densities remains bounded for math formula. No a priori smoothness is required for the limit (exact) solution.
