Back to top Results and Analysis, Efficiency Ratio. The efficiency ratio, plotted in Fig. The reason for data scattering in the efficiency ratio is the same as for the head ratio. Efficiency ratio versus delivered volumetric concentration. Back to top Results and Analysis, Power Ratio.
S m the slurry relative density.
The power ratio versus the concentration is plotted on Fig. 8. 8 shows that for the coarse sand data points display a considerably large scatter. This may be related to the phenomenon as explained for the head ratio. Power ratio versus delivered volumetric concentration. Dimensionless power versus dimensionless flow rate.
