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.
Science. Viscosity is a measurement of how resistant a fluid is to attempts to move through it. A fluid with a low viscosity is said to be thin, while a high viscosity fluid is said to be thick.. It is easier to move through a low viscosity fluid (like water) than a high viscosity fluid (like honey). Newtonian and Non-Newtonian Fluid Viscosity Most common fluids, called Newtonian fluids (yes, another thing named after that Newton), have a constant viscosity. 1  There is a greater resistance as you increase the force, but it's a constant proportional increase. In short, a Newtonian fluid keeps acting like a fluid, no matter how much force is put into it.
