  We consider thermal plasmas in a large class of superconformal gauge theories
described by a holographic dual geometry of the form $AdS_5\times M_5$. In
particular, we demonstrate that all of the thermodynamic properties and
hydrodynamic transport parameters for a large class of superconformal gauge
theories exhibit a certain universality to leading order in the inverse 't
Hooft coupling and $1/N_c$. In particular, we show that independent of the
compactification geometry, the leading corrections are derived from the same
five-dimensional effective supergravity action supplemented by a term quartic
in the five-dimensional Weyl tensor.
