Grain Bin Calculator

The Grain Bin Calculator helps users estimate the storage capacity of a grain bin by calculating volumes, total weight, bushels, and tons based on bin dimensions and grain type input.

Step-by-Step Guide to Using the Grain Bin Calculator

Step 1: Input Bin Dimensions

To start using the Grain Bin Calculator, you will need to provide key dimensions of your grain bin. Specifically, you will need the diameter and both the eave and peak heights of the bin. Follow the prompts in the input fields section:

  • Bin Diameter (feet): This is a required field for which you should enter the bin’s diameter, from edge to edge, in feet. Valid values range from 3 to 156 feet, and you can specify decimal points following steps of 0.1 feet.
  • Eave Height (feet): Enter the height of the bin up to the eave. The eave height should be at least 0 feet and should not exceed 150 feet, ensuring you use increments of 0.1 feet.
  • Peak Height (feet): Provide the height from the base to the highest point (peak) of the bin. Similar to the eave height, allow for a minimum input of 0 feet, a maximum of 150 feet, and increments of 0.1 feet.

Step 2: Specify Grain Type

Select the type of grain that your bin will contain. This is important for calculating the total weight. Choose from the following options:

  • Corn: 56 lbs/bushel
  • Wheat: 60 lbs/bushel
  • Barley: 48 lbs/bushel
  • Oats: 32 lbs/bushel
  • Soybeans: 60 lbs/bushel

Select the desired grain type from the dropdown menu, ensuring this step is completed as it influences the final calculation of weight.

Step 3: Review Resulting Calculations

Once all inputs are provided, the calculator will automatically compute the following:

  • Cylinder Volume (cubic feet): This is the volume of the main cylindrical portion of the bin. It is calculated using the formula π × (bin diameter / 2)² × eave height.
  • Cone Volume (cubic feet): This represents the volume of the conical roof section. It is calculated with (1/3) × π × (bin diameter / 2)² × (peak height - eave height).
  • Total Volume (cubic feet): The sum of the cylinder and cone volumes, representing the total volume the bin can hold.
  • Total Bushels: Derived by multiplying the total volume by 0.803 to convert cubic feet to bushels.
  • Total Weight (lbs): Computed from multiplying the total bushels by the weight per bushel of the selected grain type.
  • Total Tons: Converts the total weight in pounds to tons by dividing by 2000.

The outputs will display with formatting such that values include specified units and are rounded to appropriate decimal places for clarity.

By following these steps, you can effectively utilize the Grain Bin Calculator to determine key metrics associated with grain storage, helping you make informed decisions regarding capacity and weight management.
