The best answer to this question is that under the absolute best of circumstances the blend time for two impellers will be half the time for one impeller and the pumping capacity for two impellers will be twice the pumping capacity for one impeller. First, both of the impellers need to be axial flow (pitched-blade or hydrofoil) impellers, not radial flow. Then, the stated spacing .

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei, and can often be described by a chemical equation.
