, according to Eurocode 1, Part 4 [ 11 ], the recommended values amount to 0.25, 0.4 and 0.6. When applying the above relations, it is necessary to once again calculate the parameters determining the geometry of the flow channel each time the radius of the silo is changed. The Eq. (5) for determining the value of cos θ c , after appropriate mathematical transformations, can be written in a form that is independent of the radius of the silo: (7) cos θ c = 1 + ( e c r ) 2 + G 2 2 e c r
