The image above represents volume ratio.

To compute for volume ratio, two essential parameters are needed and these parameters are **Mass of the Liquid Metal filling the Mould Cavity, Gates and Risers (G)** and** Casting Volume (V).**

The formula for calculating volume ratio:

K_{v} = ^{G} / _{V}

Where:

K_{v} = Volume Ratio

G = Mass of the Liquid Metal Filling the Mould Cavity,Gates and Risers

V = Casting Volume

Let’s solve an example;

Find the volume ratio when the mass of the liquid metal filling the mould cavity, gates and risers is 12 and the casting volume is 24.

This implies that;

G = Mass of the Liquid Metal Filling the Mould Cavity,Gates and Risers = 12

V = Casting Volume = 24

K_{v} = ^{G} / _{V}

K_{v} = ^{12} / _{24}

K_{v} = **0.5**

Therefore, the **volume ratio** is **0.5.**

**Calculating the Mass of the Liquid Metal Filling the Mould Cavity, Gates and Risers when the Volume Ratio and the Casting Volume is Given.**

G = K_{v} x V

Where;

G = Mass of the Liquid Metal Filling the Mould Cavity,Gates and Risers

K_{v} = Volume Ratio

V = Casting Volume

Let’s solve an example;

Find the mass of the liquid metal filling the mould cavity, gates and risers when the volume ratio is 15 and the casting volume is 10.

This implies that;

K_{v} = Volume Ratio = 15

V = Casting Volume = 10

G = K_{v} x V

G = 15 x 10

G = 150

Therefore, the **mass of the liquid metal filling the mould cavity,gates and risers **is **150.**
