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.
Viscosity 1. Viscosity. Viscosity. Clear liquid above has lower viscosity than the substance below. SI symbol: Î¼, Î·. SI unit: PaÂ·s = kg/(sÂ·m) Derivations from other quantities: Î¼ = GÂ·t. Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. In. everyday terms (and for fluids only), viscosity is thickness or internal friction. Thus, water is thin, having a. lower viscosity, while honey is thick, having a higher viscosity.
