Weight, shrinkage, strength, and other properties depend upon the moisture content of Size: KB. fiber saturation point is considered as that moisture content above which the physical and mechanical properties of wood do not change as a function of moisture content.

The fiber saturation point of wood averages about 30% moisture content, but in individual species and individual pieces of wood it can vary by several percentage points from thatCited by: Moisture exchange between wood and air depends on the relative humidity and temperature of the air and the current amount of water in the wood.

This moisture relationship has an important influence on wood properties and performance. Many of the challenges of using wood as an engineering material.

This moisture relationship has an important influence on wood properties and performance. This chapter discusses the physical properties of most interest in the design of wood products.

Some physical properties discussed and tabulated are influenced by species as well as variables like moisture content; other properties tend to be independent of species. Moisture properties of wood Wood is a hygroscopic, meaning it is a material that absorbs water. Water gets into wood in three ways: as a fluid through the cell lumens through capillary tension, as vapour through the cell lumens, and as molecular diffusion through the cell walls.

The study was carried out to evaluate the effect of moisture content on some physical and gravimetric properties of black gram. Four levels of moisture content ranging from to % d.b. were used. The average length, width, thickness, geometric mean diameter, thousand seed mass and angle of repose were increased as the moisture content.

Three tropical wood species namely Iroko (Milicia excelsa), Bilinga (Nauclea diderrichii), and Tali (Erythrophleum suaveolens) were chosen.
