The relationship between mass-flow hopper half angle and the wall friction angle is presented in fig 2a&b and shows that as the wall friction angle reduces the limiting hopper angle for mass-flow becomes shallower. I.e. the higher the friction between the powder and the hopper wall, the steeper the hopper required for mass-flow.
