Some physical and frictional properties of Phule Mosambi and Kinnow 158-161

Citrus is of high importance in agriculture now days and a substantial source of income for the producing countries. Physical and frictional properties of fruits as well as oranges are important for design of postharvest handling and processing machineries. The present work was undertaken to determine the spatial dimensions, equivalent diameter, sphericity, weight,volume, specific gravity and coefficient of friction of Phule Mosambi and Kinnow or Tangerine (Citrus reticulata). The average equivalent diameter, sphericity, weight, volume and specific gravity for Phule Mosambi was 65.68 mm, 0.96, 165.14 g, 170.31 cm3 and 1000.5 kg/m3 and that of Kinnow fruits was 66.44 mm, 0.95, 156.71 g, 146.97 cm3 and 1086 kg/m3. The average coefficient of friction over ply wood, aluminium and mild steel was 039, 0.43 and 0.45, respectively for Phule Mosambi and in case of Kinnow it was 0.36, 0.41 and 0.42, respectively.
