Bodenstein number formula

\(\large{ Bo = \frac{ v \; l }{ D_a } }\) 

Where:

 Units English Metric
\(\large{ Bo }\) = Bodenstein number \(\large{dimensionless}\)
\(\large{ D_a }\) = effective axial diffusivity \(\large{\frac{ft^2}{sec}}\)  \(\large{\frac{m^2}{s}}\) 
\(\large{ l }\) = reaction length \(\large{ft}\) \(\large{m}\)
\(\large{ v }\) = velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
