The textual content involves six chapters. the 1st bankruptcy discusses cer tain empirical relationships among wooden and water, tools of measuring wooden moisture content material, elements which impact its equilib rium moisture content material, and the influence of moisture content material on wooden power. the second one bankruptcy treats the thermodynamics of moisture sorption by means of wooden, inc1uding enthalpy, entropy, and loose power alterations. The 3rd bankruptcy discusses a few of the theories which were proposed to provide an explanation for the sorption isotherms for hygroscopic ma terials equivalent to wooden. bankruptcy four considers hygroexpansion or the shrinking and swelling of wooden linked to moisture switch. bankruptcy five is anxious with how moisture strikes throughout the mobile wall of wooden in keeping with either moisture and temperature gradients. The 6th and ultimate bankruptcy discusses the theoretical and sensible elements of resistance and dielectric houses of wooden, in c1uding the rules considering their software in electric moisture meters.
