AB  - Physical properties of agricultural materials are essential in the development of machineries, equipment and devices. In this research, forty sample each of two unique varieties namely Jewel-orange flesh sweet potatoes (JOFSP) and Oriental-purple flesh sweet potatoes (OPFSP) physical properties were determined using standard methods and equations. The results show that JOFSP gave the mean length (110.68±24.59 mm), width(61.40±8.09 mm), geometric mean (39.72±8.19 mm), volume (187.78±73.85 ml), surface area (4950.00±203.32 mm2) and roundness (1.81±0.50) which were of higher values compared to that of OPFSP which gave the length (68.46±10.16 mm), width (59.32±5.82 mm), geometric mean (36.32±3.90 mm), volume (137.83±10.97 ml), surface area (4320.20±98.00 mm2) and  roundness (1.41±0.30) respectively.  JOFSP gave moisture content, thickness, mass, sphericity and true density of 58.00±10.17 %, 37.60±7.17 mm, 202.87±65.12 g, 0.35±0.08, and 1.17±0.27 g cm-3 which were of lower values compared to that of OPFSP which gave 79.32±3.84 %, 45.94±9.04 mm, 271.87±15.72 g, 0.53±0.08, and 1.89±0.14 g cm-3 for OPFSP respectively. The mean of the angle of repose and the static coefficient of friction considered for the three-separate surfaces namely plywood (9.35±2.87°, 0.17±0.05), stainless steel (8.50±3.50°,0.15±0.05)  and galvanized steel (8.30±3.20°) of lower values for JOFSP compared to that of plywood which gave (11.80±2.25°, 0.21±0.04), stainless steel (9.90±2.02°, 0.19±0.05), galvanized steel (10.90±2.28°) for OPFSP while the coefficient static of friction of stainless steel for JOFSP gave a higher value of 0.20±0.13 compared to that of 0.17±0.04 for OPFSP respectively. These findings provide engineers with valuable information for designing different handling, grading, and drying systems for industrial processing.
