High viscosity liquids will be especially prone to resisting shear stress. This idea of resistance to flow was taken a step further in the first experiment and the data collected was used to verify Stokes’ Law for a sphere falling in a liquid. In experiment #3, a falling marble was dropped in glycerin and its terminal...

Analysis of Geometric Modeling of Slot Die Lips for ECS2015

Interestingly, mercury (viscosity table and viscosity chart) has a dynamic viscosity of 1.55 cP, which is not much greater than water. But if you ask about kinematic viscosity, which is dynamic viscosity divided by the density of the fluid, then mercury has a VERY low viscosity because it is very dense.
