abstract: We investigate the accretion process for different
spherically symmetric space-time geometries for a static
fluid. We analyze this procedure using the most general black
hole metric ansatz. After that, we examine the accretion process
for specific spherically symmetric metrics obtaining the
velocity of the sound during the process and the critical speed
of the flow of the fluid around the black hole. In addition, we
study the behavior of the rate of change of the mass for each
chosen metric for a barotropic fluid.
