Find the settling velocity of a discrete spherical particle in water under conditions when Reynold's number is less than 0.5. The diameter and specific gravity of the particle are 5 × 10-3 cm and 2.65, respectively. Water temperature is 20∘ C (kinematic viscosity of water at 20∘ C = 1.01 × 10-2 cm2/sec.).
