Answer: 

hello vijay....

There are various methods available to measure the powder flow. The compendial methods include measurement of angle of repose (1), bulk density, tapped density (2) Carr's compressibility index (3), or Hausner ratio (4). With technological advances, innovative methods of characterization of powder flow such as cohesivity determination

 avalanching determination

 shear cell

 dielectric imaging

atomic force microscopy

 and penetrometry have been introduced

i would suggest you to refer N.K.Jain once in which details are given
