Which of the following represents Dispersion number? (Where D is the fluid dispersion coefficient, L is the length of spread of tracer and u is the fluid velocity)

Which of the following represents Dispersion number? (Where D is the fluid dispersion coefficient, L is the length of spread of tracer and u is the fluid velocity) Correct Answer \(\frac{D}{uL} \)

Dispersion number is a dimensionless group characterizing spread in the entire reactor vessel. The value of D determines the spread.
