WebImpeller Reynolds Number a dimensionless number used to characterize the flow regime of a mixing system and which is given by the relation Re = pNDV/r where p = fluid density, N = impeller rotational speed, D = impeller diameter, and /r = fluid viscosity. The flow is normally laminar for Re <10, and turbulent for Re >3000. WebNov 15, 2024 · Q is the volumetric gas flow at the impeller (taken as midpoint between the impeller and gas sparger for simplicity of design) in m 3 s −1. N is agitator rotational speed in revolutions per minute. D is …
