We consider the radial structure of radiatively inefficient hydrodynamicaccretion flows around black holes. We show that low-viscosity flows consist oftwo zones: an outer convection-dominated zone and an inner advection-dominatedzone. The transition between these two zones occurs at ~50 Schwarzschild radii.Comment: 11 pages, 3 figures, accepted for publication in Ap
