Richardson Number

Richardson number, abbreviated as Ri, a dimensionless number, is the ratio of the buoyancy term to the flow shear term.

 

Richardson Number formula

\(\large{ f = \frac{ Gr }{ Re^2 }  }\)

Where:

Units	English	Metric
\(\large{ Ri }\) = Richardson number	\(\large{dimensionless}\)
\(\large{ Gr }\) = Grashof number	\(\large{dimensionless}\)
\(\large{ Re }\) = Reynolds number	\(\large{dimensionless}\)
