Finding the Volume of a Storage Bin A fairly common shape for a dry- solids storage bin is a cylindrical silo with a conical collecting section at the base where the product is removed (see figure below). To calculate the volume of the contents you us the formula for a cone, as long as the height of the product, h, is less than or equal to the height of the conical section, heone. rah ifh sheone and r is the radius at heighth: r, =htang if me R. If the height of the stored product is greater than the height of the conical section, the equation for a cylinder must be added to the volume of the cone: If the height of the conical section is 3.0 m, the radius of the cylindrical section is 2.0 m and the total height of the storage bin is 10.0 m, what is the maximum volume of material that can be stored
