The plot below displays the effluent turbidity vs. critical velocity graphed on a semilog semi-log plot. Each flow state was run for 6 hours, however, the floc blanket was primarily at the high setting of 60 cm, as opposed to the desired low setting, due to air blocking the flow through the solenoid valve. There were also error in both the initial caculations of the flow rate and the tubing size. Instead of testing at a Vc range of 5 to 20 m/day a much higher Vc range of around 39 to 131 m/day. The results are display in the graph below.
