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.
Simply put viscosity is a physical property of a fluid or gas that reflects itâs tendency to flow. We commonly refer to high. viscosity fluids as being âthickâ and low viscosity fluids as being âthinâ.
