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.
Apparent Viscosity. The definition of the dynamic or shear viscosity Î· is based on the two-plates-model and defined for ideally viscous fluids, i.e. the viscosity is constant independent of the shear rate applied to the sample.
