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.
(March 2009). The apparent viscosity of a fluid depends on the shear rate at which it is measured. The apparent viscosity of a dilatant fluid is higher when measured at a higher shear rate (Î·â is higher than Î·â), while the apparent viscosity of a Bingham plastic is lower (Î·â is lower than Î·â).
