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 is defined as the resistance of a fluid to deformation under shear stress. It is generally considered as flow behavior or resistance to pouring. Viscosity is described as the internal resistance of a fluid to flow and may be considered as a measure of fluid friction. Viscosity is an important parameter in the paint industry processing stage.
