PREDICTING METHOD OF TERMINAL VELOCITY FOR GRAINS

Homin Song, J. B. Litchfield

Open publisher page 30 citations

Abstract

ABSTRACT Terminal velocities in air of com, soybeans, wheat, oats, and barley were measured. The actual terminal velocities of the grains were found to be related to the theoretical terminal velocities of the grains by one of two dimensionless geometric shape factors. Based on the shape factors and the theoretical values, the terminal velocity of the five seed grains can be predicted. The maximum error of prediction was 15.7%.
