Wood boards ¼ inch thick have a moisture content of 60% by mass. If the diffusivity of water in wood is taken as 3 x 10^-10ft^2/s, estimate the time for the wood to have a moisture content of 5% at its center if the air surrounding the boards was originally dry and hD (the convective mass transfer coefficient) is 1 x 10^-8ft/s.
