Fineness factor calculations based on Equation 2 and data from table 2: Fineness factor (%) – Equation 2 = ½ x (100 + 93) = 96.5. The results using Equations 1 and 2 are the same, but there is an advantage in using Equation 2 because products contain the % material passing through mesh sizes 10 and 50.
