RESISTANCE OF ALFALFA CUBES, PELLETS AND COMPRESSED HERBAGE TO AIR-FLOW

The airflow resistance of bulk alfalfa cubes, alfalfa pellets and comp ressed herbage alfalfa was measured in the laboratory for the range of airflow of 0.003 to 1.0 m3.s-1.m-2. The effect of fines concentration up to 25% (dry mass basis) on airflow resistance of alfalfa pellets a lso was measured. The pressure drop versus airflow data on a log-log s caled plot were nearly linear and parallel for all the material types considered. Coefficients of Hukill-Ives' and Shedd's equations were de termined for airflow resistance data of alfalfa cubes, pellets, and co mpressed herbage.
