Abstract
(1) Moisture Contest (MC) = green weight - oven dry weight ÷ oven dry weight (2) Specific Gravity = oven dry weight ÷ weight of the same volume of water as the wood sample volume at designated MC (3) Based on 80 cu. ft. per cord of solid wood (4) Assumption: @ 0% M.C., Hardwoods = 8600 BTU/lb and Softwoods = 9300 BTU/lb. To calculate BTU/lb @ 20% MC = (.833 lbs. of wood) (BTU/lb at 0% MC) - (.167 lbs. H20) (1210 BTU for H20 vaporization). Therefore, Hardwoods = 6962 BTU/lb and Softwoods = 7545 BTU/lb. @ 20% MC.
