SERRANO, D.A.; SANCHEZ-SILVA, F.; KLAPP, J.  e  MEDINA, A.. The Hagen-Beverloo law for outflow of granular solids from holes on side walls. Rev. mex. fis. [online]. 2015, vol.61, n.3, pp.207-210. ISSN 0035-001X.

In this work we have analyzed experimentally the lateral mass outflow rate m, for cohesionless granular solids (coarse grains) through circular orifices of diameter D made on side walls of bins. Experiments were performed to determine the influence of the wall thickness of the bin w, and of the grain diameter d on m. Geometrical and physical arguments are given to get a general correlation for m as a function of D, d, and w. This correlation can be termed the Hagen-Beverloo law for orifices on side walls.
