Zewdu School of Engineering and Information Technologies, PO Box 1888, Adama, Ethiopia Tel: +251 911 828912/500267, netmail: zewdu.abdi@adama-university.net ABSTRACT In this probe scatter seminal fluiding of tef seminal fluid was considered. In order to predict tinge flight on and off record book, after developing a numeral relationship, simulation of particle movement on and off saucer of a rotate disc was undertaken. The terminal velocity and coefficient of quarter promote of tef seed were determined experimentally in laboratory. intercommunicate distance of particle thrown off the disk was mensurable by alter different particle property (such as wet content, coefficient of friction, TGM and pa rticle density) and machine parameters (such as cone weight and angular velocity). The projected distance of a particle change magnitude with increase in wet content of seed, broadcaster revolution per minute and inclination of disc with the horizontal. The increase in wet content was associated with increase in coefficient of friction, which do cave in effect on-the disc particle motion. The increase in moisture content has influence also on thousand impress mass, particle size, sphericity, particle density and coefficient of drag force which aroused off-disc particle trajectory. This investigation showed the possibility of utilize a spinning disc spreader in order to broadcast tef seed, which could commute broadcasting of tef seed by hand manually. Broadcasting using spreaders resembles the farmers practice, which use manual broadcasting of seeds unlike seed drills, which involves rows.
