A standard starting point for the impeller diameter ( ) is often between of the tank diameter ( Speed (

A standard design spreadsheet is generally divided into several key sections: Tank agitator power calculation - My Engineering Tools

You can find downloadable templates from various engineering providers:

The volumetric flow rate (pumping capacity) generated by the impeller is calculated using the pumping number (Nq).

Change RPM, impeller size, or fluid viscosity to see immediate effects on power consumption.

A sample XLS template for agitator design calculations might include the following columns:

for turbulent applications. For high-viscosity fluids using anchors or helical ribbons, can exceed Clearance (

The power number is a dimensionless quantity that depends on the impeller type and NRecap N sub cap R e end-sub . The spreadsheet should feature a lookup table for Npcap N sub p based on the selected impeller. C. Power Calculation (P) The power required (in Watts) is calculated as:

In the world of chemical engineering, the quest for the perfect mix often begins not with a wrench, but with a spreadsheet. This is the story of "The Perfect Blend," a journey through the cells and formulas of an agitator design calculation. The Problem: The Gloopy Mess
