Question : Calculate the heating time when four such boards are stacked together.Note 1: Don’t use Heissler charts to answer this question.Note 2: You’re free to make assumptions regarding any value you think you need in order to solve the problem. Just explain your reasoning behind your assumption in a logical manner.Note3: please explain clearly and step by step Heat sterilization of lumber, timbers, and pallets is used to kill insects toprevent their transfer between countries in international trade. This is analogous tofood sterilization by heat. A typical requirement here is that the slowest heating pointof any wood configuration be held at 56 °C for 30 minutes. Consider hot air heating ofwooden boards that maintains their surface temperature at 70 °C. The boards arestacked outside and in the winter time they can be considered to be at 0 °C when theyare brought in for heating. The thermal diffusivity of the wood is 9*10-8 m?/s.

Question : Calculate the heating time when four such boards are stacked together.

Note 1: Don’t use Heissler charts to answer this question.

Note 2: You’re free to make assumptions regarding any value you think you need in order to solve the problem. Just explain your reasoning behind your assumption in a logical manner.

Note3: please explain clearly and step by step

Heat sterilization of lumber, timbers, and pallets is used to kill insects to
prevent their transfer between countries in international trade. This is analogous to
food sterilization by heat. A typical requirement here is that the slowest heating point
of any wood configuration be held at 56 °C for 30 minutes. Consider hot air heating of
wooden boards that maintains their surface temperature at 70 °C. The boards are
stacked outside and in the winter time they can be considered to be at 0 °C when they
are brought in for heating. The thermal diffusivity of the wood is 9*10-8 m?/s.
