In handling and processing of agricultural products, air or water is often used as a transport medium for separating the desirable product from unwanted materials. When an air stream is used for separating a product from its associated foreign materials, such as straw and chaff, knowledge of aerodynamic characteristics of all the particles involved is necessary. This helps to define the range of air velocities for effective separation of the grain from foreign materials. For this reason, the terminal velocity (Vt) has been used as an important aerodynamic characteristic of materials in such applications as pneumatic conveying and their separation from foreign materials.
