Aslab of dry wood of 4-in thickness and sealed edges is exposed to air of 40% relative humidity. assuming that the two unsealed surfaces of the wood immediately jump to an equilibrium moisture content of 8 lb h2o per 100 lb of dry wood, determine the time for the moisture content at the center of the slab to reach 1% of the equilibrium value using the semi-infinite slab solution. assume a diffusivity of water of 6.00e-006 cm2/s.
