Bulk density refers to the mass of a substance per unit volume, excluding any voids or air spaces.

• It is a measure of how densely packed the particles or molecules are in a given volume.

• Bulk density is commonly used in industries such as mining, agriculture, and pharmaceuticals.

• It is calculated by dividing the mass of the substance by its volume.

• For example, the bulk density of a soil sample can indicate its compaction ...read more

Target mean strength is the desired strength level of a product or material.

• It is the strength level that a product or material is designed to meet or exceed.

• It is determined based on the intended use and expected stresses on the product or material.

• It is often used in quality control to ensure that products meet the desired strength level.

• For example, the target mean strength of a steel beam used in construction may b...read more
