Using a laboratory unit, the resistance to airflow through bulk lentils (Lens culinaris M.) and the effect of seed moisture content, variety, method of fill, direction of airflow, and percent fines on the resistance to airflow was determined for an airflow range of 0.003 to 0.6 m3.s-1.m-2. An increase in moisture content of Laird lentils from 10.4 to 19.9% resulted in a 22.5% decrease in resistance to airflow. The resistance to airflow of Eston lentils was 3 to 27% higher than the resistance of Laird lentils at airflow rates between 0.0028 to 0.0272 m3.s-1.m-2, and was 1% to 6% lower at airflow rates between 0.0272 and 0.5926 m3.s-1.m-2. The dense fill of Laird lentils produced a bulk density about 9% greater and a resistance to airflow about 50% higher compared with the loose fill. The resistance of Laird lentils to horizontal airflow was one-half of the resistance to vertical airflow. A linear equation was developed to relate the increase in pressure drop with an increase in percent fines.
