In this work we discuss the general validity of a phenomenological correlation for the mass flow rate of dry non cohesive granular material that outflows, due to the gravity, from slots in very thin vertical sidewalls of bins. The correctness of such a formula is analyzed by comparing it to other correlations published elsewhere which reports cases of very large, similar and very small channel width W relative to its length D.
