Density (unit weight) is a measure of weight per unit volume and is expressed in lbs/ft³ or kg/m³. The density of fresh concrete is similar to the density of hardened concrete. After the unit weight is determined ...

Chapter 8. Pulp and Paper - Rural Tech
www.ruraltech.orgIt is also common to express pulp yield as air-dry or oven-dry tons of pulp per cord or other unit of wood volume. Alternatively, the reciprocal of these measures indicates the number of cords or other wood unit required per ton of pulp. In addition to the factors discussed above, these measures are affected by wood density. Yield is
