This is a continuation of the
Process Intensifier - Optimization with CFD: Part 1 paper.
Using the power numbers and the usual power number correlation,
the amount of power required by the impellers for each unit is:
| N=1750 RPM |
Radial Process Intensifiers |
Axial Process Intensifiers |

The power draw of the Process Intensifiers with axial impellers
is about an order of magnitude less than the two designs with
radial impellers. The size of the motor is an indicator of the cost
of each unit. A 0.5 HP unit will be less costly than a 10 HP unit.
Just the same, it is amazing that any of these small units can
agitate up to 1.584 Million Gallons (6 Million Liters) per day
(at 1100 GPM (250 m3/hr)).
