How Much Corn Will a 55-Gallon Drum Hold? A Comprehensive Guide
Determining exactly how much corn a 55-gallon drum can hold isn't as simple as just plugging numbers into a formula. The answer depends significantly on several key factors:
1. Type of Corn:
- Shelled Corn: This is the most common type used for feed or processing. The kernels are removed from the cob. Shelled corn has a relatively consistent density.
- Ear Corn (on the cob): This significantly impacts the volume due to the cobs taking up considerable space. You'll get considerably less volume compared to shelled corn.
2. Moisture Content:
The moisture content of the corn drastically affects its density. Dry corn will have a higher volume per weight compared to wet corn. The moisture level is usually expressed as a percentage. For example, 15% moisture content means 15% of the weight is water.
3. Method of Filling:
How you fill the drum influences the final volume. If you carefully pour the corn, you'll likely achieve a higher density than if you simply shovel it in, leaving air pockets.
4. Shape and Size of the Drum:
While most 55-gallon drums are relatively standardized, slight variations can exist. It's also important to consider that the drum is not perfectly cylindrical; the ends are usually slightly domed, further complicating precise volume calculations.
Approximate Estimates (Shelled Corn):
While precise calculation is difficult without specifying moisture content and filling method, we can offer approximate estimates based on commonly cited figures. One commonly used figure states that a bushel of shelled corn occupies approximately 1.25 cubic feet. A 55-gallon drum has a volume of approximately 7.35 cubic feet.
Therefore, a rough approximation is:
7.35 cubic feet / 1.25 cubic feet/bushel ≈ 5.88 bushels
A bushel of shelled corn weighs approximately 56 pounds. This provides a very rough estimate of:
5.88 bushels * 56 pounds/bushel ≈ 329 pounds of shelled corn.
However, this is just a ballpark figure. The actual amount could vary by +/- 10% or more depending on the factors listed above. Using ear corn will significantly reduce this amount.
How to Get a More Accurate Measurement:
For a more precise measurement, consider these options:
- Weigh the Corn: The most accurate method involves weighing the filled drum. Subtract the weight of the empty drum to find the weight of the corn. Use the known weight and moisture content to calculate the volume.
- Use a calibrated scale: Weigh the corn before adding it to the drum, ensuring a higher accuracy than just measuring the filled drum.
- Consult agricultural resources: Local agricultural extension offices or feed suppliers often have precise data for corn density under various conditions.
In conclusion: A 55-gallon drum can hold approximately 329 pounds of shelled corn, but this figure is a rough estimate and can vary considerably. The most accurate method is to weigh the corn itself. Always account for moisture content and the type of corn when calculating expected volume.
