The viscosity is given in Pascal second, Pas, millipascal second, mPas (SI units), or in poise or centipoise (cP). 1 Pas = 10 P, but 1 mPas = 1 cP. The viscosity of water at 20 掳C is 鈭 1 mPas. Most practical materials such as suspensions, emulsions, and gels show a ...
For water, νwater is 10−6 m2 s−1, while for blood, νblood is on the order of 3–4 × 10−6 m2 s−1. 10.02.1.3.2 Newtonian fluid Newtonian fluids have a linear relationship between shear stress, τ, and velocity gradient, du/dy, in the direction perpendicular to the flo...
The dynamic viscosity of the solution is: Zs ¼ Zw t s rs t w rw ð3Þ where ηs is the viscosity of the test solution (Pas), ηw is the viscosity of water (Pas), ts is the timing of the runoff of the tested solution (s), tw is the timing of the runoff of water (...

In our experience, reliable data are obtained when the relative viscosities of polymer solutions are in the range of 1.1–1.4. Temperature control is critical to obtaining reliable measurements of dilute solution viscosity, and thus mounting the viscometer in a water bath controlled to +/− 0.01...
This method is suitable to determine kinematic viscosity of liquid petroleum products ( It refers to Newtonian liquids ), and its unit is m2/s. Generally in actual utilization, the unit is mm2/s. The dynamic viscosity is equal with the result which use kinematic viscos...
