In this work we report experiments carried out to describe the features of the mass flow rate of dry cohesionless granular material that flows, only due to gravity, out from circular orifices at the sidewall of silos with thin wall thickness, w. This study shows that the classical Hagen’s correlation for the mass flow rate is essentially correct for this case. Finally, we show graphically, in a three-dimensional plot, the evolution of the flow rate for continuous variations of the parameters D and w
