How to measure the density of wood?

– the wood density air-dry, which is called wood density », is the ratio between the mass and the volume of the sample conditioned at approximately the humidity level; – the “infradensity of drink », ratio between the mass and the volume saturated with water or « green volume » of the sample.

What are the factors that influence the density of wood?

Wood density also influences the cost of transporting logs and sawn wood, the purchase price of wood by weight, pulp yield; wood density is a key factor for the assessment of forest biomass and bioenergy. In principle, the water content increases with the decrease in the density of the wood.

What is Wood Density?

Density is mass per unit volume. The density of wood relates strictly to the solid substance of the wood, without taking into account the water and air in the wooden structure., The density of wood or specific density of wood is measured in kg / m3 and varies from one species of wood to another.

How does wood density affect wood weight?

Together, the amount of ashes and extractives will affect the weight of the wood differently depending on the species. Iroko, for example, contains 2.35% mineral substances. Oven-dry density is the density based on the weight and volume of the wood when it is oven-dried.

How to calculate the density of a wood?

Density is expressed in units of mass divided by volume, such as grams per cubic centimeter (g/cm3), kilograms per cubic meter (kg/m3), or pounds per cubic foot (lb/ft3). The higher the number, the denser the wood.
