Elmanın Bazı Geometrik ve Hidrodinamik Özellikleri ile Zedelenme Parametrelerinin Belirlenmesi

Object: In this study, physical properties such as, moisture content, size, mass, volume  density, sphericity, projection area, rolling resistance coefficient and hydrodynamic properties in water such as terminal velocity, drag force, buoyant force and bruise volume, bruise area, absorbed energy of the apple fruits (Arapkizi and Amasya varieties) were determined. Material and Methods: In this study, two different apple varieties and for each variety  55 samples and total 110 samples were used. Physical properties such as, moisture content, size, mass, volume density, sphericity, projection area, rolling resistance coefficient and hydrodynamic properties in water such as terminal velocity, drag force, buoyant force and bruise volume, bruise area, absorbed energy of the apple fruits (Arapkizi and Amasya varieties) were determined. Results: In terms of dimensional properties, the Arapkizi variety is larger than the  Amasya variety. Terminal velocity, drag force and buoyant force in water were found as 0.414 ms-1, 0.327 N, 1.874 N for the Arapkizi variety, 0.417 ms-1, 0.264 N, 1.571 N for Amasya variety respectively. Conclusions: In the case of fruit dropping on the two impact surfaces, a relationship  was found between bruise area with volume and drop height. Absorbed energy was increase, with depend on the increasing of the initial height of drop onto different surface.
