Bioreactors, where vortex is formed, another dimensionless number, __________ is useful.

In a bioreactor, if at a particular time the oxygen transfer rate is 23 kg.h^-1, then the oxygen uptake will be

For turbulent flow, Reynolds number is correlated with power number as (where K, a constant which depends on the container geometry and shape of stirrer; Re_i, is Reynolds number for agitator; D_i, stirrer diameter and N, stirrer speed)

For laminar flow, Reynolds number is correlated with power number as (where K, a constant which depends on the container geometry and shape of stirrer; Re_i is Reynolds number for agitator; D_i, stirrer diameter and N, stirrer speed)

Turbulent flow range of mixing speed is obtained for
