Discharge of air through an orifice
http://performativedesign.com/definitions/air-flow/air-flow-coefficient/ WebFeb 2, 2011 · If a material is discharged from an unventilated hopper, air will have to enter through the orifice countercurrent to the discharging material. This will set up an adverse pressure gradient, causing a reduction in the mass flow rate. This can easily be evaluated from Equation (9) if the permeability of the material is known.
