Notes:
A dimensionless solids flowrate for discharge from an orifice in the bottom of a containing vessel is shown to be a function of a parameter that measures the importance of fluid drag to particle inertia. The analysis assumes a linear relation between presure gradient and slip velocity and compares favorably to experiment within its supposed region of applicability for three experimental situations: the self-induced, air-impeded discharge of fine particles from a conical hopper; the discharge of particles from a sealed egg-timer-like vessel; and the air-assisted discharge of particles through an orifice.
