# Dynamic Shear Viscosity

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Dynamic shear viscosity, abbreviated as $$\mu$$ (Greek symbol mu), is the resistance to shearing flow of a fluid, where adjacent layers move parallel to each other in different ways.

## Dynamic Shear Viscosity Formula

 $$\large{ \mu = \frac { F \; y }{ A \; u } }$$

### Where:

$$\large{ \mu }$$  (Greek symbol mu) = dynamic shear viscosity

$$\large{ A }$$ = area of each plate

$$\large{ F }$$ = applied force

$$\large{ y }$$ = separation distance

$$\large{ u }$$ = speed of movement
