The angle of the repose has been utilized in many branches of science to show the solids flow properties. The angle of the repose is a characteristic that is related to inter particulate resistance or friction to the movement among the particles. The angle of repose test results is very dependent on the method used. As a result of the segregation of material and consolidation, experimental difficulties arise or Powder's aeration formed as a cone.
The formula for Angle of Repose.
The angle of repose is specified by θ.
It is expressed as, Tan θ = µ = h/r.
Where,
h is the height,
r= radius of the pile
and µ is the coefficient of friction.
