1 Purpose and Scope

1.1 This Standard gives equations and graphs that can be used to estimate the flow rate of specific grains and oilseeds through horizontal and vertical orifices for mass flow situations (Ref: Chang et al., 1984, 1988, 1990a). They can be applied to flow from bins and hoppers during emptying and appropriate for specific ranges of moisture content.
