  The equilibrium of a resistive axisymmetric plasma with purely toroidal flow
surrounded by a conductor is investigated within the framework of the nonlinear
magnetohydrodynamic theory. It is proved that a) the poloidal current density
vanishes and b) apart from an idealized case the pressure profile should vanish
on the plasma boundary. For the cases of isothermal magnetic surfaces,
isentropic magnetic surfaces and magnetic surfaces with constant density, the
equilibrium states obey to an elliptic partial differential equation for the
poloidal magnetic flux function, which is identical in form to the
corresponding equation governing ideal equilibria. The conductivity, which can
not be either uniform or a surface quantity, results however in a restriction
of the possible classes of equilibrium solutions, e.g., for the cases
considered the only possible equilibria with Spitzer conductivity are of
cylindrical shape.
