Newtonian Fluid 1
Newtonian Fluid 1 :
(n.) Drilling Fluids. A fluid that has a constant viscosity at all shear rates at a constant temperature and pressure, and can be described by a one-parameterrheological model. An equation describing a Newtonian fluid is given below. Water, sugar solutions, glycerin, silicone oils, light-hydrocarbon oils, air and other gases are Newtonian fluids. Most drilling fluids are non-Newtonian.
