Airflow resistance of shelled corn was measured in both horizontal and vertical directions at eight airflow rates between 0.76 and 28.6 mVm2.min and at three different bulk densities. Data were fitted to the Ergun equation and multipliers for horizontal airflow were determined. For airflow rates above 6 mm^-min, horizontal airflow resistance was about 58% of the vertical resistance. For airflow rates at or below 6 mm^-min, horizontal resistance was about 45% of the vertical resistance.
