The bound for the shear viscosity-to-entropy density ratio is employed in the AdS/CFT and fluid/gravity correspondence setup is shown to provide a theoretical bound for the post-Newtonian parameter in the Casadio-Fabbri-Mazzacurati black string solution, matching the observational/experimental bound. The Casadio-Fabbri-Mazzacurati-AdS black brane is shown to converge to the Schwarzschild-AdS black brane, corroborating to a conjecture by Emparán. Hydrodynamical aspects of black holes and black strings are discussed, in the context of the Plateau-Rayleigh phenomena.
