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.
At low stress, plots for composites with starch volume fraction [less than] 0,41 display similar curvature to that obtained for PHEE. Relative viscosity is defined as the ratio of composite viscosity to that of unfilled PHEE at the same shear stress.
