Abstract

In basic physics books practically anything is discussed about the flux of granular materials, even though grains systems are widely present in the everyday life. In this work was developed a relatively simple experimental system to study the flow of rice and sugar grains out of a cylindrical silo with a circular aperture at the bottom. Measurements were repeated at different diameters of the circular holes and different initial heights of the grains column. For didactic motivations, the same system was used to measure the flow of water. The results clearly illustrate the differences between the two kinds of fluids and can be easily replicated in the classroom. (AU)
