For example, at "room temperature", water has a nominal viscosity of 1.0 × 10 -3 Pa∙s and motor oil has a nominal apparent viscosity of 250 × 10 -3 Pa∙s. Simply put, this quantity is the ratio between the pressure exerted on the surface of a fluid, in the lateral or horizontal direction, to the change in velocity of the fluid as you move down in the fluid (this is what is referred to as a velocity gradient). That is why they are often referred to as simply viscosity. Shear viscosity and dynamic viscosity are much better known than the others.
