  We perform axisymmetric two-dimensional radiation-hydrodynamic simulations of
super-Eddington accretion flow and outflow around black holes to examine the
properties of radiation and outflow as functions of the black hole mass and the
accretion rate onto the black hole ($\dot M_{\rm BH}$). We find that the
$\dot{m}_{\rm BH} (\equiv \dot{M}_{\rm BH}c^2 /L_{\rm Edd})$ dependence of
$L_{\rm rad}/L_{\rm Edd}$ and $L_{\rm mech}/L_{\rm Edd}$ found for stellar-mass
black hole can apply to the high mass cases, where $L_{\rm rad}$ is the
radiation luminosity, $L_{\rm mech}$ is the mechanical luminosity, $c$ is the
speed of light, and $L_{\rm Edd}$ is the Eddington luminosity. Such
universalities can appear in the regime, in which electron scattering opacity
dominates over absorption opacity. Further, the normalized isotropic mechanical
luminosity $L_{\rm mech}^{\rm ISO}/L_{\rm Edd}$ (evaluated by normalized
density and velocity at $\theta=10^\circ$) exhibits a broken power-law
relationship with ${\dot m}_{\rm BH}$; $L_{\rm mech}^{\rm ISO}/ L_{\rm Edd}
\propto{\dot m}_{\rm BH}^{2.7}$ (or $\propto {\dot m}_{\rm BH}^{0.7}$) below
(above) ${\dot m}_{\rm BH}\sim 400$. This is because the radial velocity stays
nearly constant (or even decreases) below (above) the break with increase of
$\dot m_{\rm BH}$. We also find that the luminosity ratio is $L_{\rm
mech}/L_{\rm rad}^{\rm ISO} \sim$ 0.05 at ${\dot m}_{\rm BH} \sim 100$, which
is roughly consistent with the observations of NLS1, 1H 0323+103.
