Vt = (g*dp^2*(raup - rauf))/(18*(viscocity)).
Where dp = diameter of particle.
raup = density of particle.
rauf = density of fluid.
Where dp = diameter of particle.
raup = density of particle.
rauf = density of fluid.

This is wrong answer.
Vt is proportional to square of dia.
So if dia is doubled, Vt should be four times not one - fourth of original.
