## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are best for corrosive fluid applications?
**A**: For corrosive environments, Hastelloy or plastic impellers (PP/PVDF) offer superior chemical resistance compared to stainless or carbon steel.

### Q: How does blade angle affect impeller performance?
**A**: Blade angle determines fluid flow patterns and mixing efficiency. Steeper angles create more axial flow, while shallower angles promote radial flow in agitator assemblies.

### Q: What factors determine the optimal number of blades?
**A**: Blade count affects torque requirements and mixing intensity. More blades provide smoother operation and higher shear, while fewer blades reduce power consumption and cavitation risk.
