Silo Design Calculator

Silo Design Calculator

This calculator is useful for planning system layouts by helping you estimate silo and tank sizes. Our thanks to Frazier Bulk, Inc., on whose spreadsheet it is based.

Assumptions: 1. *Standard Diameters Available - 6', 8', 9', 10', 12', 13.5', 16'
2. *Standard Sidewalls - 2.5' increments
3. *Standard Inlet Diameter - 20"
4. *Standard Outlet Diameter - 18".
5. *Inlet & Outlet Ring Vertical Depth is 4".
