Resumen:
This is an experimental study of the discharge of seeds in a silo in a mass flow regime. It demonstrates how the flow parameters involved in Beverloo´s equation (C and k) can be correlated with some of the shape parameters belonging to the seed grains. Results show that the concept of empty annulus introduced through the parameter k is dependent on the size and on the specific surface area. Besides, the circularity of the grains, alone, is not enough to predict the value of k in a grain discharging process.
