Calculating Volume and Drying Time

Understanding how to calculate the volume of logs and estimate drying time is essential for efficient wood processing and firewood preparation.

• Calculating Volume of Logs:
  • Board Feet: Board feet is a common unit of measurement for lumber. One board foot is equal to a piece of wood that is 1 inch thick, 12 inches wide, and 12 inches long.
  • Cords: A cord is a unit of measurement for firewood. A standard cord is a stack of wood that is 4 feet high, 4 feet wide, and 8 feet long, for a total volume of 128 cubic feet.
  • Doyle Log Scale: The Doyle Log Scale is a common formula for estimating the board foot volume of a log. The formula is: (Diameter - 4)^2 * Length / 16. For example, a log that is 16 inches in diameter and 10 feet long would have an estimated volume of (16 - 4)^2 * 10 / 16 = 90 board feet.
• Estimating Drying Time:
  • Moisture Content: The moisture content of wood is the percentage of water in the wood. Freshly cut wood can have a moisture content of 50% or more. Firewood should be dried to a moisture content of 20% or less for optimal burning.
  • Drying Time Factors: The drying time of firewood depends on several factors, including the species of wood, the size of the pieces, the climate, and the stacking method.
  • Rule of Thumb: As a general rule of thumb, firewood should be dried for at least six months to a year before burning. Hardwoods like oak and maple may take longer to dry than softwoods like pine and fir.
  • Formula: A rough estimate of drying time can be calculated using the following formula: Drying Time (months) = (Initial Moisture Content - Target Moisture Content) / Drying Rate. The drying rate varies depending on the climate and stacking method, but a typical drying rate is around 5% per month.
