NRe=Da2⋅N⋅ρμcap N sub cap R e end-sub equals the fraction with numerator cap D sub a squared center dot cap N center dot rho and denominator mu end-fraction (where Dacap D sub a = impeller diameter, = density, = viscosity) . Calculated using the dimensionless Power Number ( Npcap N sub p ), which varies by impeller type (e.g., for propellers, for pitched blades, and for Rushton turbines).
Designing an industrial agitator requires balancing fluid dynamics with mechanical integrity. The primary goal is to determine the power needed to achieve a specific mixing intensity while ensuring the shaft can withstand the resulting torque and bending forces . agitator design calculation pdf download verified
Let's consider an example of agitator design calculation: NRe=Da2⋅N⋅ρμcap N sub cap R e end-sub equals
