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.
Kinematic viscosity is the absolute viscosity of a fluid divided by its mass density. The dimensions of kinematic viscosity are area divided by time; the appropriate units are meter squared per second. Viscosity is measured with various types of viscometers and rheometers.
