Selected Geometric Characteristics, Hydrodynamic Properties, and Impact Parameters of Quince Fruit (Cydonia vulgarisPers.)

In this study, selected geometric properties, including linear dimensions; sphericity; mass of fruit; projected area; surface area; true density; volume; static coefficient of friction against different materials; hydrodynamic properties in water, such as terminal velocity, drag force, and buoyant force; and impact parameters, such as coefficient of restitution, absorbed energy, bruise area, and bruise volume, of two varieties of quince fruit were determined. The selected geometric and hydrodynamic properties were found to be considerably similar with both varieties in quince. The smallest values of bruise area and bruise volume were obtained with the corrugated board. The coefficient of restitution decreased with the increase in the drop height for each variety.
