a.) What is the terminal settling velocity of a particle with a specific gravity of 1.4 and a diameter of 0.01 mm in 20 degrees celcius water?
b.) Would particles of the size in part (a) be completely removed in a settling basic with a width of 10 meters, a depth of 3 meters, a length of 30 meters, and a flow rate of 7,500 m3/day?
c.) What is the smallest diameter particle of specific gravity 1.4 that would be removed in the sediment basin described in part (b)?
