total moisture

n
all of the moisture in and on a consignment or sample of coal.
DISCUSSION — In a consignment or sample of coal in which surface moisture is present, total moisture is the sum of surface moisture and pore moisture. In consignments or samples of coal in which some portion of the as-mined moisture may have been removed by partial drying, total moisture may be less than the inherent moisture. Total moisture is commonly determined by quantitatively air drying a sample and then assaying residual moisture in the air-dried sample; thus, total moisture is the sum of the air-dry loss and the residual moisture adjusted to the as-received basis.
