Difference between apparent viscosity and kinematic viscosity
Newtonian fluid: A fluid that obeys Newton’s law. Viscosity depends only on temperature and not on the shear rate; τ is proportional to D. Non-Newtonian fluids: They do not obey Newton’s law τ/D=f(D). The viscosity at a certain value of (τ/D) is denoted by ηa, and it is known as the apparent viscosity. For solutions, the relative viscosity μr is commonly used to represent the ratio of the solution viscosity μ to the solvent viscosity μ
