| Abstract Nowadays, bulk solid materials (granules) are subject in various industries, including food, agriculture, pharmaceuticals, packaging, polymer production, and recycling. Investigating the mechanical properties and kinetic equations of granular material flow is of significant importance and complexity as well. The characteristics of these materials, such as apparent density and settling velocity, influence their behavior. Due to the non-uniform motion and flow of granular materials and the presence of void spaces between particles, various factors need to be considered in computations related to granular flow. Measuring the mass flow rate and velocity of granular materials is essential for efficient and optimal use of energy and raw materials in industries, and it must be controlled. Given the complexity of measuring the flow rate of granular materials using traditional or modern methods, theoretical and formula-based calculations of granular material flow would assist in the accuracy of sensors measuring the flow rate of granular materials in industrial production lines. The aim of this research is to investigate and theoretically calculate the velocity of granular material flow in gravity fall in transfer pipeline from any tank or silo using the Beverloo equation. In this study, considering the necessary correction coefficients and constants, the velocity of grain flow (in this case, wheat) in the transfer pipeline from silo is calculated to evaluate the performance of a grain flow rate measuring sensor. |
