2. During a snowstorm, the fluoride feeder or blender as shown below run out of the feed chemical. The rapid mix tank is connected to a 5-km-long distribution pipe. The flow rate into the rapid-mix tank is 0.44 m'/s and the volume of the tank is 2.5 m'. The velocity in the pipe is 0/17 m/s. If the fluoride concentration in the rapid-mix tank is 1 mg/L when the feed chemical stops, how long will it be until the concentration of fluoride is reduced 0.01 mg/L at the end of the distribution pipe? The fluoride may be considered a non-reactive chemical. Fluoride 0,17 m/s Q - 0,44 m's Q- 0,44 5 km C- 1.0 mg/L

Question
Transcribed Image Text:2. During a snowstorm, the fluoride feeder or blender as shown below run out of the feed chemical. The
rapid mix tank is connected to a 5-km-long distribution pipe. The flow rate into the rapid-mix tank is 0.44
m/s and the volume of the tank is 2.5 m’. The velocity in the pipe is 0/17 m/s. If the fluoride
concentration in the rapid-mix tank is 1 mg/L when the feed chemical stops, how long will it be until the
concentration of fluoride is reduced 0.01 mg/L at the end of the distribution pipe? The fluoride may be
considered a non-reactive chemical.
Fluoride
= 0,17 m/s
Q = 0,44 m's
