NRe=ρ⋅N⋅D2μcap N sub cap R e end-sub equals the fraction with numerator rho center dot cap N center dot cap D squared and denominator mu end-fraction is the rotational speed ( is the impeller diameter ( Using the Power Number ( Npcap N sub p agitator design calculation

the tank diameter, while radial impellers (like flat-blade turbines) may be larger for specific high-shear applications. Mixing and Agitation Calculations Source: PumpFundamentals

Calculate the required motor power by adding a safety margin (usually 10–20%) and accounting for drive efficiency (gears, seals). $$P_motor = \fracP\eta_drive \times SafetyFactor$$ $$P_motor = \fracP\eta_drive \times SafetyFactor$$
