The image above represents volume shrinkage. To calculate volume shrinkage, two essential parameters are needed and these parameters are **Mould Volume (V _{m})** and

**Volume of Casting at 20°C (V**

_{o}).**The formula for calculating the volume shrinkage:**

ε_{v}= ^{Vm – Vo} / _{Vo} x 100%

Where:

ε_{v} = Volume Shrinkage

V_{m} = Mould Volume

V_{o} = Volume of Casting at 20°C

Let’s solve an example;

Find the volume shrinkage where the mould volume is 30 and the volume of casting at 20°C.

This implies that;

V_{m} = Mould Volume = 30

V_{o} = Volume of Casting at 20°C = 3

ε_{v}= ^{Vm – Vo} / _{Vo} x 100%

ε_{v} = ^{30 – 3} / _{3} x 100%

Then, ε_{v} = ^{27} / _{3} x 100%

ε_{v} = 9 x 100%

ε_{v} = **900%**

Therefore, the **volume shrinkage **is **900%.**
