At a shear rate of 10 s-1, the apparent viscosity of non-Newtonian liquid was found to be 1.0 Pa.s. At a shear rate of 100 s-1, the apparent viscosity of the same liquid was found to be 0.5 Pa.s. If the liquid follows power law behavior, determine the apparent viscosity (in Pa.s) at a shear stress of 10 Pa

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.
