How Wall Friction Affects Hopper Angles

What is wrong with this statement? Mass flow is dependent on wall friction properties and is affected by the smoothness and steepness of the hopper wall and the properties of the bulk material. If you design your hopper for 70°, it may achieve mass flow; but, it may flow in mass flow at a shallower angle say, 65° or may also require 85°.

Bulk solids basics: Flowability

The simple definition of flowability is the ability of a bulk solid to flow. But there is a scale between free flowing and non-flowing. Further, the flowability is not an inherent material property. Rather, it is the result of material physical properties and/or the equipment that is used for handling, storing and processing.
