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:

 Units English Metric
\(\large{ \mu }\)  (Greek symbol mu) = dynamic shear viscosity \(\large{\frac{lbf-sec}{ft^2}}\) \(Pa-s \)
\(\large{ A }\) = area of each plate \(\large{ft^2}\) \(\large{m^2}\)
\(\large{ F }\) = applied force \(\large{lbf}\) \(\large{N}\)
\(\large{ y }\) = separation distance \(ft\) \(m\)
\(\large{ u }\) = speed of movement \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
