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.
a rheological term taken from the rheometer reading performed by a Mud engineer on drilling fluid and it is expressed in the centipoise. Centipoise is the level of force needed to move one layer of fluid in relation to another. APPARENT VISCOSITY: The apparent viscosity applies to non-Newtonian fluids..
