Characterization Of The Physical Properties Of Periwinkle

ABSTRACT

An investigation was carried out on some physical properties of periwinkle (Littorniealittorea) to characterize periwinkle based on their physical properties. The study was conducted on some selected physical properties, namely; size, shape, volume, surface area, bulk density, weight, and angles of repose. Results obtained revealed that the periwinkle had size range of 21.43mm, volume range of 2.48mm3, bulk density of 0.478kg/m3, solid density of 1.05kg/m3weight of 2.36g, sphericity of 0.479, surface area of periwinkle as cone 3 16.32cm2, surface area of periwinkle as sphere is 284.2 lcm2,porosity of 0.496%. Also the angle of repose of the periwinkle on three different material surfaces were concluded and the results were as follows; 1.0400 with metal material 0.8310 respectively. The analysis of the work showed that the periwinkle does not have spherical shape, it tends towards conical shape because the of area.
