A slurry containing solid particles having a density of 2.4 g/cm3 and ranging in diameter from 0.001 to 0.1 in. is fed to a settling tank 10 ft in diameter. Water is pumped into the tank at the bottom and overflows the top, carrying some of the particles with it. If it is desired to separate out all particles of diameter 0.02 in. and smaller, what flow rate of the water in gpm, is required?
