The document provides information to design a cylindrical storage bin for 450 tons of soda ash. It includes the material properties and design requirements. The summary is: The dimensions of the bin are estimated as a diameter of 5m, conical bottom height of 6.5m, and cylindrical height of 11.5m. The minimum bottom opening diameter is 141.5mm. With a bottom diameter twice the minimum, the solid flow rate out of the bin would be 146 kg/s. The vertical pressure on the bottom is 29.3 kPa and equivalent liquid pressure is 211 kPa.
