Re=ρ⋅N⋅D2μcap R e equals the fraction with numerator rho center dot cap N center dot cap D squared and denominator mu end-fraction = Fluid density ( = Agitator speed ( = Impeller diameter ( = Dynamic viscosity ( Power Consumption (
Such integrated calculations are essential for producing a design that is not only fluid-dynamically sound but also mechanically reliable and safe. agitator design calculation xls
Below is a for a typical pitch-blade turbine / marine propeller in a baffled tank. Re=ρ⋅N⋅D2μcap R e equals the fraction with numerator
The core of the design is calculating the required power and impeller Reynolds number. A. Impeller Reynolds Number ( Reicap R e sub i Determines if the flow is laminar or turbulent. "If we overpower it, we shear the product
"We can't just guess a bigger motor," Raj said, tapping his pen against his clipboard. "If we overpower it, we shear the product. If we under-power it, we ruin the batch. We need to calculate the Reynolds number, the power number, and the specific pumping rate."
