The emptying
angle of repose ([[theta].sub.e]) was determined by quintuplicate using a method similar to that presented by Koocheki et al.
Where, =
angle of repose, h= height of heap, r= radius of base of heap circle.
Determination of
Angle of Repose. Flow-ability of common beans was measured using the
angle of repose that will be useful in material handling equipment.
Based on the particle size distribution, these microspheres are expected to display impaired flowability, as confirmed by the
angle of repose, Hausner ratio, and Carr's index (Section 3.4).
The
angle of repose was measured according to Silva et al.
The bulk and tapped densities were found to be 0.5120.02 and 0.640.09 for Clarithromycin powder, while the hausner's ratio,
angle of repose and the compressibility index was found to be 1.250.02, 30.00.02 and 20.02 respectively.
The
angle of repose was measured using the fixed funnel method adapted by Iwuagwu and Onyekwelli [7].
Moreover, a sieve analysis was performed and an
angle of repose was determined.
Powder mixtures of different formulations were evaluated for
angle of repose, bulk density, tapped density, and compressibility index.
