A flat slab of wood 50 mm thick containing 90 mol/m³ moisture is being dried from the top 3 surface by passing hot dry air. The equilibrium moisture content at the surface of the wood due to the drying air blown over it is held at 6.6 mol/m³ moisture. The drying can be assumed to be represented by diffusivity of 8.0 x 10- 0-6 m²/h. 1. What is the moisture content at a point 2 cm beneath the slab surface after 24 h? 2. What is the required time for the moisture content at the slab center to reach 50 mol/m³?
