Agitation Scaleup Calculation Does the scaleup from smaller to larger scale based on criteria like equal tip speed, power per unit volume, equal Reynold's number, equal shaft speed.
Mechanical Agitator Power Requirements for Liquid Batches _____ Application Equations Mechanical agitator power requirements for liquid batches are calculated by determining the power number, N P, for a given system and correcting for motor, gearing and bearing losses. Design specification of the motor is then determined by
axial-flow pattern impellers are the most suitable agitators in such cases. This article extends impeller-designing recommendations for particle suspension with many axial-flow impellers types in wide range of concentrations and particle diameters. It is written to help designers to

Calculating Torque and Bending Moment are important in desigining vertical mount mixers. Enter the motor nameplate horsepower (HP), shaft speed (RPM), shaft length (in), and mixer head diameter (in) in the cells below. The torque an bending moment are actual values, a safey factor of at least 1.5 should be used in the design of […]
These are made available to help you do preliminary mixer sizing, mixtank volume calculations, some mixer mechanical design calcs, etc. The mixer selection program allows you to calculate flow rates and power draw of mixing impellers, see what the agitator will provide for tip speed and tank turnovers per minute, and give you some rough estimates on tank mixer sizings.

Program for Design and Drawing of Agitator / Mixer asks for size of vessel and properties of liquid. For Axial Flow Turbine, TurboProp, Paddle, Anchor, Anchor/Paddle or Gate you can select either Bolted or Welded Impeller. You can decide proportion of Diameter of Impeller to Diameter of Vessel, and expected Reynold's Number.
For given type of agitation flat paddle impeller is used as given below: After selection of impeller dimensionless number Reynold's number is calculated as given below Re = ρ*N*d 5 / µ From generic agitator curve, as shown in Fig.1, impeller power number is calculated based on calculated …

Agitators are usually designed to operate in a filled tank free of external flow and chunks of solids. If it will be operating during fill or drain, or in the presence of a net side flow, that must be part of the mechanical design. Assume nothing when it comes to long unsupported shafts. RE: sizing an agitator. 786392 (Petroleum) 2 May 12 04:52.
One of the key design parameter to calculate when implementing such an agitator is the size (power) of the motor which will drive the agitator. WARNING : the calculation is only to define the power required to run the agitator, however it is not giving assurance that the agitation in the tank will be adequate, further calculations are required.

Following the calculations you did I got power of around 583kW for the agitator which seems really high. The viscosity of the fluid is 4.5cp and density is 1210kg/m3. Could you please let me know if the power value is reasonable.
