  We study the properties of the shock waves for a viscous accretion flow
having low angular momentum in presence of synchrotron cooling. We present all
possible accretion solutions in terms of flow parameters. We identify the
region of the parameter space for steady and oscillating shocks and show the
effect of various energy dissipation processes on it. We discuss the role of
the shock waves while explaining the observations from black hole candidates.
