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.
The values obtained are 'apparent viscosity' or 'apparent shear viscosity' values. They represent one point of the viscosity function only. A viscosity function displays Î· over shear rate. The shear conditions need to be specified for apparent viscosity values.
