A settling tank in a water treatment plant is designed for a surface overflow rate of 30 m3/(day x m2). Assume specific gravity of sediment particles = 2.65, density of water (ρ) = 1000 kg/m3, dynamic viscosity of water (μ) = 0.001 N x s/m2, and Stokes' law is valid. The approximate minimum size of particles that would be completely removed is:
Correct : b
