How do impeller design and geometry affect power requirements and mixing effectiveness?
Impeller design and geometry play a crucial role in both power requirements and mixing effectiveness, making them central to any agitator power calculation. Different impeller types—such as propellers, turbines, or pitched-blade designs—create unique flow patterns that influence how energy is transferred into the liquid. Larger diameters and specific blade angles can improve circulation but may require more power. By including impeller geometry in an agitator power calculation, engineers can balance efficiency, energy consumption, and desired mixing results.
