Predicting Equilibrium Moisture Content of Wood by Mathematical Models

Ten sorption models were tested on the wood-water system using data available in the literature. They were tested solely on the basis of how well they could functionally relate the data for equilibrium moisture content and relative humidity. The two-hydrate form of the Hailwood and Horrobin model is the most accurate of those tested that are written as moisture content equal to a function of relative humidity. The Pierce model is the most accurate of those tested that are written as relative humidity equal to a function of moisture content.
