Explain rate of particles is proprotional to the squares

Reference no: EM13214427

In air and according to Stokes Law, the settling rate of particles is proprotional to the squares of their diameters, if they have the same densities. If emitted particles with a given diameter are found to settle out after 7 days, how long would it take a particle of the same material with 1x the diameter to settle out?

t2/t1 = (d1/d2)²
t2 = t1(d1/d2)²
t2 = 7(d1/1d1)²
t2 = 7(1)²
t2 = 7
