Context & Assumptions

Anchor impellers are utilized for mixing highly viscous products in jacketed vessels where low-speed, close-clearance agitation is required. This calculation determines the shaft power and motor requirements specifically for the laminar flow regime, where viscous forces dominate. Accurate power estimation is critical for drive train sizing and managing mechanical heat generation in temperature-sensitive processes.
