Digestion Essay The path of digestion begins in the mouth when food is broken down mechanically, into smaller pieces, by the teeth and tongue. The complex carbohydrates found in the food are also broken down chemically with the help of the enzyme (ptyalin), found in saliva.
apparent viscosity. (fluid mechanics). The value obtained by applying the instrumental equations used in obtaining the viscosity of a Newtonian fluid to viscometer measurements of a non-Newtonian fluid. 1  Facebook. 2  Twitter.
1 Viscosity is another type of bulk property defined as a liquidâs resistance to flow. When the intermolecular forces of attraction are strong within a liquid, there is a larger viscosity. 2  Viscosity can be not only a fluidâs resistance to flow but also a gasâ resistance to flow, change shape or movement. The opposite of viscosity is fluidity which measures the ease of flow while liquids such as motor oil or honey which are âsluggishâ and high in viscosity are known as viscous.
