While I cannot supply a pre-verified PDF, the above guide contains the core calculations you need. For an official, certified design manual, consult “Mixing Equipment (Impeller Type) – Design Recommendations” by the Engineering Equipment and Materials Users Association (EEMUA) or “Process Equipment Design” by Brownell & Young.

If you are searching for a reliable, containing standard agitator design calculations, you are likely tired of scattered Excel sheets and outdated textbooks. In this article, we provide a roadmap to verified calculation methodologies, including where to obtain the definitive PDF guide for mechanical and process design.
