Typical values of G for a detention time of 15 to 30 minutes vary from 20 to 75 second_1. Figure 10-5
is supplied to aid the designer in determining the horsepower requirement for flocculation systems. To
use the figure, select G and detention time desired. (Note: flocculation tank volume can be determined
from the design flow rate and the detention time.) Enter chart at detention time and find power.
Correct by multiplying by the appropriate factor contained in the table accompanying the figure.
