conversion of arb to air dried basis
The % oven-dry solids or %OD is calculated by: Moisture content can be calculated two ways: % Moisture content dry basis = (wet weight – dry weight)/dry weight *100. This expression is the most commonly used expression of moisture content in wood. It is easily converted to %OD by subtracting the %MC dry basis from 100. Ver artículo
What is the difference between ARB and ADB? – FastAdvices
ADB – Air-Dried Basis. In coal sample analysis, ADB neglects the presence of moistures other than inherent moisture while DB (dry-basis) leaves out all moistures, including surface moisture, inherent moisture, and other moistures. ARB – As-Received Basis.
