$\sf\colorbox{cyan}{☦ Definition of viscocity ☦}$

Viscosity is a measure of a fluid's resistance to flow.

It describes the internal friction of a moving fluid.

$\sf\colorbox{cyan}{☦ unit ☦}$

The unit of viscosity, accordingly, is newton-second per square metre, which is usually expressed as pascal-second in SI units. ... Kinematic viscosity is the absolute viscosity of a fluid divided by its mass density.

Answer:

Good morning....❣❣

Your answer.....

definitions. Informally, viscosity is the quantity that describes a fluid's resistance to flow. Fluids resist the relative motion of immersed objects through them as well as to the motion of layers with differing velocities within them. ... The SI unit of viscosity is the pascal second [Pa s], which has no special name.
