Generally speaking, kinematic viscosity (cSt) relates to absolute viscosity (cP) as a function of the fluid’s specific gravity (SG) according to the equations in figure 3. Figure 3. Viscosity Equations As simple and elegant as these equations look, they hold true only for so-called Newtoni...
that if a pressure of 1 Pa is applied for 1 second, the plate will move the same distance as the distance between the two plates. Centipoise (cP) is also a common unit for dynamic viscosity — 1 cP is the viscosity of water around room temperature. The imperial units, pound-seconds ...
A sticky subject We can say that viscosity is the resistance a material has to change in form. This property can be thought of as an internal friction.Laminar Flow To get a good feel for viscosity, we need to first digress and remember laminar flow. If a fluid or gas is flowing...

It is measured by determining the time in seconds required for a fixed volume of fluid to flow a known distance under gravity through an orifice of a calibrated viscometer at a controlled temperature. Typical instruments used are Zahn cups & Ford Cups of distinct types, as well as capillary ...
The measured kinematic viscosity is usually expressed in seconds required for outflow. The efflux time can be converted to centistokes (cSt) by a standard formula. Centistokes (cSt) = K value × outflow time - (C value ÷ outflow time), centipoise (cP) = centistokes × specific grav...

Therefore, for a crude oil with a specific gravity of 0.89 and dynamic viscosity μ = 38 cP, kinematic viscosity is calculated from Eq. (1.9) as ν=38/0.89=42.7 cSt. In the petroleum industry, two additional kinematic viscosity units for liquids are used. These are Saybolt Seconds Uni...
