DescriptionMuch information is available on the specific gravity of wood on a dry weight over green volume and dry weight over dry volume basis. This paper presents the conventional specific gravity on a green weight over green volume basis. The relative specific gravities of bark and wood chips may be helpful in finding way to remove bark particles from chips.
