The natural outdoor usage of the wood does not exceed a moisture content of 19% .Hence, it is not a reasonable value.
Given wet weight of wood = 1315.8g
Oven dry weight = 612g
Moisture content MC% = (Wet weight of wood - Weight of Oven dry wood) / Weight of Oven dry wood × 100
(1315.8 - 612) / 612 x 100
= 703.8 / 612 x 100 = 115%
In the normal use, the moisture content of wood varies between 8% and 25% by weight. The natural outdoor usage of wood does not exceed a moisture content of 19%. Hence, it is not a reasonable value.
