The table below helps to identify the mixing intensity required for a given scale of mixing.
| TYPE | DESCRIPTION | MIXSCALE | TYPICAL APPLICATION |
|---|---|---|---|
| MILD | LITTLE SURFACE MOTION, NO SPLASH, MILD RIPPLE | 1 | MOST STORAGE APPLICATIONS.LOW VISCOSITY BLENDING OF LIQUIDS WITH MINIMAL DIFFERENCE IN SPG'S & VISCOSITY. VISCOSITY IN THE RANGE OF 100 CPS AND BELOW. LIGHT SOLIDS MOVING ON TANK BOTTOM, NO SUSPENSION. |
| 2 | |||
| 3 | |||
| MODERATE | SLOW ROLLING LIQUID SURFACE OCCASIONAL WAVE WITH LITTLE SPLASH | 4 | LOW TO MEDIUM VISCOSITY BLENDING WITH SP.G. DIFFERENCE LESS THAN 0.6 WITH VISCOSITIES GENERALLY BELOW 5000 CPS.SOLIDS MOVING OFF BOTTOM BUT NOT SUSPENDED ANYMORE THAN 20% THROUGHOUT TANK. EASY HEAT TRANSFER. |
| 5 | |||
| 6 | |||
| VIGOROUS | SOME SPLASH WITH BOILING ACTION AT SURFACE, OCCATIONAL VORTEX | 7 | MEDIUM VISCOSITY LIQUID/LIQUID BLENDING. SP.G. DIFFERENCE LESS THAN .85 WITH VISCOSITY LESS THAN 10,000 CPS. MODERATELY SUSPENDED SOLIDS THROUGHOUT 75% ON TANK. GOOD HEAT TRANSFER. |
| 8 | |||
| VIOLENT | SPLASHING AND LARGE WAVE FORMATIONS, ERRATIC VORTEXING | 9 | LIQUIDS WITH VISCOSITIES LESS THAN 25,000 CPS WITH SP.G. DIFFERENCE OF 1.0. SOLIDS SUSPENDED TO COMPLETE UNIFORMITY. |

* MixScale is Bulk Fluid Velocity / 6
Bulk fluid velocity (BFV) is calculated from the corrected impeller pumping capacity (cubic feet per minute), divided by tank cross sectional area (sq ft). Units are ft/min.
