Oven dry mass formula

Web8.3 To calculate the specific gravity of the specimen, the sum of the final surface-dry mass and the mass of any specimen remaining on the filter paper from Subsection 8.1.5 is substituted for A in the denominator of Equation 1 or 2. Webof combustion per unit oven dry mass, expressed in the unit J/dry g, whereas, GHV is defined as the heat of combustionper unit wet mass, expressed in the unit J/wet g. Oven dry mass refers to the mass of fuel without any moisture (moisture content equals to zero); wet mass refers to the mass of fuel, which contains moisture content above zero.

WebThen, the dry weight would be the weight of the sample when it has achieved this oven-dry water activity level. Under common ambient conditions of 25 °C and 30% RH, an oven set to 95 °C would create an oven-dry water activity of 0.01 aw inside the oven, assuming that the vapor pressure in the oven is the same as the air. WebW 3 = weight of container after drying the sample . From these weights we can know weight of water W W as weight of container with moist sample minus weight of container with dry sample. W w = W 2 - W 3 . And weight of solids W S as weight of container after drying the sample minus weight of empty container. W s = W 3 - W 1
