Webhopper design is substantial. For the materials in this study, hopper half angles range from 6° to 33°. Outlet size slightly increases with increasing hopper half angle (reducing wall friction) in order to maintain mass flow. Whilst perhaps counter-intuitive, this is because the shallow hopper walls tend to support a proportion of the major Web(FEM). Their study introduced the dependency of internal friction angle (φ), hopper half angle (α), wall friction coefficient (μ) and dilatancy angle (ψ) to predict the mass flow rate constant C in Beverloo equation [14]. The equation takes the form by FEM results as follows: C = 0.58 1−cos m α sin 5/2α (1.08 – 0.0164 ψ 352
