Abstract
The aim of this study is to use the Python language to design an application program for grain properties, then use a database for computer applications to predict the physical, mechanical, and aerodynamic characteristics of some grains. Also, the study of the validation of a computer application program with data from experimental equations. The physical, mechanical, and aerodynamic properties were determined from previous research. For physical properties, the mean dimensions and weight of grains were measured. The average arithmetic and geometric mean diameters, surface area, projected area, volume and bulk and true density, roundness, sphericity, aspect ratio, porosity, and moisture content were calculated. For mechanical properties, all compressing forces were measured. The reduction milling force percentage, axial and transverse strain, elongation, Poisson ratio, elasticity, and compactness were calculated. For aerodynamic properties, the mean static repose and angle of friction, and terminal velocity were measured. The static coefficients of friction and the drag coefficient were calculated. The results indicate that the properties will provide the necessary and available data for the design of grain processing machines; therefore, they represent a step in the right direction towards mechanizing grain processing. The application program of grain properties was highly accurate and can be used to calculate and describe the different characteristics as physical, mechanical and aerodynamic, for different grains.
