Impeller Clearance and Spacing

In tall agitated tanks, multiple impellers are often used to improve circulation and narrow the distribution of shear and energy dissipation. Generally, these impellers are spaced away from each other by a distance equal to one impeller diameter. However, to avoid splashing and the formation of a vortex, the top
