More with viscosity

[scrilla103]

Viscosity is measured in SI units labeled: kg/m s (kilogram per meter second). Can anyone clarify what each separate unit would represent. All I can get think of is how much the liquid resists movement; so does this unit represent the force that it resists with? Any help would be appreciated.

Those are the units when you reduce them. The actual units are pressure *time (Pascal-seconds). The physical interpretation of that is

 

If a fluid with a viscosity of one Pa·s is placed between two plates, and one plate is pushed sideways with a shear stress of one pascal, it moves a distance equal to the thickness of the layer between the plates in one second
