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 the measure of the internal friction in a liquid or the resistance to a flow. Low viscosity fluids flow easily (water, alcohol); High viscosity fluids pour slowly (molasses, cold honey, etc.).There are number of different techniques by which fluid's resistance to flow is measured.iscosity is the measure of the internal friction in a liquid or the resistance to a flow.
