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 resistance of a liquid to flowing is its viscosity.   Viscosity is a property arising from friction between neighboring particles in a fluid  that are moving at diffâ¦erent velocities. In  liquids, it could be considered the thickness. For example, maple  syrup has a higher viscosity than water.
