The normal price of the angles had the smallest deviation, becoming 44.eight° ± one.5°. Hence, the most beneficial General dynamic flow security, as a result, was determined for Sn powder, for character one products. By observing the nature from the stream in the course of the measurement with the DAOR, security can even be verified in a constant rolling movement in any way analyzed frequencies. The character with the move adjusted most significantly with growing frequency of Al powder. At reduced frequencies, Al powder confirmed rolling movement and, progressively, even a cataracting movement appeared.
