Predicting moisture content from basic density and diameter during air drying of Eucalyptus and corymbia logs

In air drying of Eucalyptus urophylla and Corymbia citriodora logs for the production of charcoal it is necessary to be able to predict when logs have reached the required moisture content of ≤ 35%.This study is aimed to produce models using basic density and diameter to predict the moistu...
