u=π⋅D⋅N60u equals the fraction with numerator pi center dot cap D center dot cap N and denominator 60 end-fraction is in RPM and is in meters. Standard baffles are usually of the tank diameter ( ) to prevent vortexing and ensure top-to-bottom turnover. 3. Power Consumption Calculations

Required pumping rate, degree of turbulence, or blend time.

Essential for shear-sensitive or high-shear applications. agitator design calculation xls

Before starting any calculation, your Excel sheet should have a designated input section for the following parameters: Tank diameter ( ), liquid height ( ), and the number of baffles. Fluid Properties: Liquid density ( ) and dynamic viscosity (

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 : Laminar flow. : Turbulent flow. Step 2: Determine Power Number ( Npcap N sub p u=π⋅D⋅N60u equals the fraction with numerator pi center

): This is a dimensionless constant specific to the impeller type (e.g., for a Rushton turbine, for a hydrofoil).

Impeller type (e.g., pitched blade, Rushton turbine), impeller diameter ( ), and rotational speed ( 2. Sizing the Impeller and Tank Fluid Properties: Liquid density ( ) and dynamic

P=Np⋅ρ⋅N3⋅D5cap P equals cap N sub p center dot rho center dot cap N cubed center dot cap D to the fifth power

For a standard "square batch" (where liquid height equals tank diameter), the impeller diameter is typically of the tank diameter (

The core of your XLS will be the power calculation, which varies based on the flow regime.
