For drying (2 m2) wood by solar energy (energy from the sun) the concentration of water at 2.9 mm into the surface of wood is 0.75 kg/m 3 and at 44 mm into the surface is 2 kg/m 3. Given that the diffusion coefficient of water in wood is 3.71X10-7 m 2 /sec ; Calculate the required time in hours to dry 1.1 kg of water out of the wood.

Solar kilns come in two main configurations; Solar kiln - Where the kiln design relies on the glasshouse principle. It traps light energy as heat when it passes through the cladding. External solar collectors are not required (Palmer Kleinschmidt 1992). An example of this type is used by the Queensland Forestry Service (see figure below), where they use a roof and three walls …
