The Volumetrical, Geometrical and FrictionalProperties of White Mulberry (Morus albaL.) Fruits

Abstract

The volumetrical, geometrical and frictional properties of white mulberry fruits (Morus albaL.) determined at a moisture content of 13.89% (d.b.). The mean values of the fruit mass, porosity, fruit volume, fruit and bulk densities values of white mulberry fruits were found as 1.06 g, 75.3%, 0.53 cm3, 1911.7 kg/m3and 454.0 kg/m3, respectively. The mean values of the surface area, sphericity and geometric mean diameter and were 4.16 cm2, 71.02% and 11.5 mm, respectively. The angle of repose of the white mulberry fruits was found as 22.1?and also, the mean values of dynamic and static coefficient of friction against plywood, chipboard, galvanized steel, rubber and mild steel surfaces were determined and the highest dynamic and static coefficients of friction values of white mulberry fruits were found for rubber surface.
