Bingham Number

Bingham number ( \(Bm\) ) (dimensionless number) is used to study the flow of Bingham plastics.

Bingham Number FORMULA

\(\large{ Bm = \frac { \tau_y   l }    { \mu v }  }\)         

Where:

\(\large{ Bm }\) = Bingham number

\(\large{ l }\) = characteristic length

\(\large{ \tau_y }\)  (Greek symbol tau) = yield stress

\(\large{ \mu }\)  (Greek symbol mu) = dynamic viscosity of fluid

\(\large{ v }\) = velocity
