The bulk density is illustrated by the image above. To calculate bulk density, four essential parameters are needed, and these parameters are Dried Weight (W), Density of Water (ρw), Soaked Weight (W), and Suspended Weight (S).

**The formula for calculating bulk density:**

BD = ^{Dρw}/_{W – S}

Where:

BD = Bulk Density

D = Dried Weight

ρ_{w} = Density of Water

W = Soaked Weight

S = Suspended Weight

Let’s solve an example;

Find the bulk density when the dried weight is 6, the density of water is 10, the soaked weight is 14 and the suspended weight is 9.

This implies that;

D = Dried Weight = 6

ρ_{w} = Density of Water = 10

W = Soaked Weight = 14

S = Suspended Weight = 9

BD = ^{Dρw}/_{W – S}

So, BD = ^{(6)(10)}/_{(14 – 9)}

BD = ^{(60)}/_{(5)}

BD = 12

Therefore, the **bulk density **is **12g/cm³.**

**Calculating the Dried Weight when the Bulk Density, the Density of Water, the Soaked Weight and the Suspended Weight are Given**

D = ^{BD(W – S)} / _{ρw}

Where:

D = Dried Weight

BD = Bulk Density

ρ_{w} = Density of Water

W = Soaked Weight

S = Suspended Weight

Let’s solve an example;

Find the dried weight when the bulk density is 10, the density of water is 4, the soaked weight is 8 and the suspended weight is 5.

This implies that;

BD = Bulk Density = 10

ρ_{w} = Density of Water = 4

W = Soaked Weight = 8

S = Suspended Weight = 5

D = ^{BD(W – S)} / _{ρw}

D = ^{10(8 – 5)} / _{4}

That is, D = ^{10(3)} / _{4}

D = ^{30} / _{4}

D = 7.5

Therefore, the **dried weight **is **7.5g.**

**Calculating the Density of Water when the Bulk Density, the Dried Weight, the Soaked Weight and the Suspended Weight are Given**

ρ_{w} = ^{BD(W – S)} / _{D}

Where:

ρ_{w} = Density of Water

BD = Bulk Density

D = Dried Weight

W = Soaked Weight

S = Suspended Weight

Let’s solve an example;

Find the density of water when the bulk density is 14, the dried weight is 10, the soaked weight is 16 and the suspended weight is 12.

This implies that;

BD = Bulk Density = 14

D = Dried Weight = 10

W = Soaked Weight = 16

S = Suspended Weight = 12

ρ_{w} = ^{BD(W – S)} / _{D}

ρ_{w} = ^{14(16 – 12)} / _{10}

So, ρ_{w} = ^{14(4)} / _{10}

ρ_{w} = ^{56} / _{10}

ρ_{w} = 5.6

Therefore, the **density of water **is **5.6 cm.**

**Calculating the Soaked Weight when the Bulk Density, the Dried Weight, the Density of Water and the Suspended Weight are Given**

W = ^{Dρw} / _{BD} + S

Where:

W = Soaked Weight

BD = Bulk Density

D = Dried Weight

ρ_{w} = Density of Water

S = Suspended Weight

Given an example;

Find the soaked weight when the bulk density is 20, the dried weight is 15, the density of water is 8 and the suspended weight is 2.

This implies that;

BD = Bulk Density = 20

D = Dried Weight = 15

ρ_{w} = Density of Water = 8

S = Suspended Weight = 2

W = ^{Dρw} / _{BD} + S

W = ^{15(8)} / _{20} + 2

So, W = ^{120} / _{20} + 2

W = 6 + 2

W = 8

Therefore, the **soaked weight **is **8.**

**Calculating the Suspended Weight when the Bulk Density, the Dried Weight, the Density of Water and the Soaked Weight are Given**

S = W – ^{Dρw} / _{BD}

Where:

S = Suspended Weight

BD = Bulk Density

D = Dried Weight

ρ_{w} = Density of Water

W = Soaked Weight

Let’s solve an example;

Find the suspended weight when the bulk density is 12, the dried weight is 11, the density of water is 7 and the soaked weight is 3.

This implies that;

BD = Bulk Density = 12

D = Dried Weight = 11

ρ_{w} = Density of Water = 7

W = Soaked Weight = 3

S = W – ^{Dρw} / _{BD}

S = 3 – ^{11(7)} / _{12}

Then, S = 3 – ^{77} / _{12}

S = 3 – 6.41

S = – 3.41

Therefore, the **suspended weight **is **– 3.41.**
