Viscosity describes the resistance of a liquid in flowing, informally described as the "thickness" of a fluid, and in principle, it has no direct relationship with density. The bulk density of a material is the ratio of the mass to the volume (including the interparticulate void volume) of an untapped powder sample. What is the difference between density and bulk density? As Table 1 displays, both 625 and 0 of soy protein are larger than whey protein. The tapped density is different thanks to the change of mass ratio in the protein mixture. This is the density of a substance including all pores remaining in the material ( a). This leads to an incorrect density value. Dry-bulk density is defined as the mass (weight) of the dry solids divided by the total volume of the wet sample; that is, dry-bulk density is the ratio of the mass of the mineral grains to the total volume. If one is found, dig down to the top of this zone and make a level surface. 2. However, the viscosity may influence the density determination depending on the method used. It is the mass of many particles of the material divided by the volume they occupy. 2.1. This research .
