It is on the image.
![1. Scaling.
(a) Considering a spherical particle is moving in a fluid with initial velocity v. The speed
of the particle decreases due to the drag force. Here we define the “stop distance" as the
travel distance until the sphere stops. Given the “stopping distance" can be expressed as
a x Re × D, derive the "a".
Assumption: pi =ps
(b) Based on the equation, the stopping distance is reduced by Lb. What is that “b"?
r = radius of the sphere
D=diameter of the sphere
v = velocity of the sphere
µ = viscosity of the fluid
P; = density of the fluid
P; = density of the particle
