EFFECT OF MOISTURE CONTENT ON ANGLE OF REPOSE AND FRICTION COEFFICIENT OF WHEAT GRAIN

Abstract

This study was carried out to determine the angle of repose of three varieties of wheat (Bani Suwayf 3, Giza 168 and Seds 1) at four different levels of grian moisture contents 9.30,10.0,11.11 and12.5 % (w. b). Also to determine the coefficient of friction at the same moisture contents and four different friction surfaces of plywood, galvanized steel, plastic and rubber. The angle of repose increased linearly with the increase of moisture content for all varieties under study.The static coefficient of friction generally increased with the increase of moisture contents.
