Please answer me Mass Transfer 1 clearly

Pine logs are dried to remove the moisture. The moistuce content of the solid surface is in equilibrium with air and can be assumed constant at 5%. The initial concentration (moisture content) is 30% and the maximum permissible is 15%. If the logs are 12.2m long with a diameter of 0.3m, Determine the time necessary for them to dry. (Deff=1107m2/s)
