The image above represents force settling ratio | coarse particles. To calculate force settling ratio for coarse particles, three essential parameters are needed and these parameters are **Density of Particle a (ρ _{a}), Density of Particle b (ρ_{b}) **and

**Density of Fluid (ρ**

_{f}).**The formula for calculating force settling ratio:**

d_{a}/d_{b} = (^{ρb – ρf}/_{ρa – ρf})

Where:

d_{a}/d_{b} = Force settling ratio

ρ_{a} = Density of Particle a

ρ_{b} = Density of Particle b

And then, ρ_{f} = Density of Fluid

Let’s solve an example;

Find the force settling ratio when the density of particle is 12, density of particle is 14 and the density of fluid is 10.

This implies that;

ρ_{a} = Density of Particle a = 12

ρ_{b} = Density of Particle b = 14

And also, ρ_{f} = Density of Fluid = 10

d_{a}/d_{b} = (^{ρb – ρf}/_{ρa – ρf})

That is, d_{a}/d_{b} = (^{14 – 10}/_{12 – 10})

d_{a}/d_{b} = (^{4}/_{2})

d_{a}/d_{b} = 2

Therefore, the **force settling ratio **is **2.**
