  We consider the spherically symmetric black hole solution of the
Randall-Sundrum (RS) model. This asymptotically-Schwarzschild solution was
found by Abdolrahimi, Cation, Page and Yaghoobpour-Tari (ACPY-solution). We
investigate the specific properties of the accretion disk around ACPY black
hole having astrophysical size and mass. The energy flux and temperature
distribution are obtained and compared with the Schwarzschild ones. We also
present the spectral energy distribution of the accretion disk around RS black
holes, when the transfer function is taken into account. Thus we confirm a full
agreement of the accretion rate in RS model with the GR predictions. Using
recent data on the high-mass X-ray binary Cygnus X-1 and on the Galactic centre
black hole candidate Sgr A* we model the accretion in the RS model.
