Solving for fall, settling or terminal velocity.

## Inputs:

acceleration of gravity (g)
particle diameter (d)
density of particle (ρp)
density of medium (ρm)
viscosity of medium (μ)

## Conversions:

acceleration of gravity (g)
= 0
= 0
meter/second^2
particle diameter (d)
= 0
= 0
meter
density of particle (ρp)
= 0
= 0
gram/meter^3
density of medium (ρm)
= 0
= 0
gram/meter^3
viscosity of medium (μ)
= 0
= 0
