Abstract
A simple experimental technique was developed for the measurement of v elocity profiles of slow flowing, coarse granular materials in mass-fl ow conical hoppers. The measured profiles were shown to be unaffected by the presence of material surcharge above the cone, independent of m aterial discharge rate, and strongly dependent upon the roughness of t he internal walls.
