摘要：
Experiments are described in which the behavior of powders in hoppers was simulated by measuring the rate of flow through funnels. A glass funnel with a stem 32 mm long and an internal diameter of 4. 4 mm and a brass funnel with an opening of 3/8 inch diameter and no stem were used. The angle of repose was measured from the slope of a pile in the case of the metal balls. In other cases the angle was measured by tilting a trough full of the powder and measuring the angle at which flow started. Measuring results are tabulated and discussed in terms of practical recommendations.
