A settling tank needs to be constructed to remove 90% (on a mass basis) of the suspended solids in a 575 cubic feet per minute (cfm) water flow from a local waste stream. A laboratory settling test using a 6 ft column has provided the following data on the contents and settling of particles in the waste water. Fraction of Settling time mass collected 1 min 2% 5 min 9% 10 min 17% 20 min 32% 30 min 44% 45 min 58% 1 hour 68% 2 hours 90% 4 hours 99% 100% Long time For geometric proportions, take length equal to four times width and width equal to twice depth. What should the dimensions of this settling tank be? Express your answers in feet.
