Bingham Number

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

Bingham Number FORMULA

\(Bm = \frac { \tau_y   l }    { \mu v } \)          \( Bingham \; number   \;=\;  \frac { yield \; stress  \;\;x\;\; characteristic \; length  }    {  dynamic \; viscosity   \;\;x\;\; velocity  } \)

Where:

\(Bm\) = Bingham number

\(l\) = characteristic length

\(\tau_y\) (Greek symbol tau) = yield stress

\(\mu\) (Greek symbol mu) = dynamic viscosity of fluid

\(v\) = velocity
