The image above represents speed of sound in molten metal.

To compute for speed of sound in molten metal, two essential parameters are needed and these parameters are **Melting Temperature (T _{m})** and

**Molecular Weight (M).**

The formula for calculating speed of sound in molten metal:

u_{s} = 16(^{Tm} / M)^{0.5}

Where:

u_{s} = Speed of Sound in Molten Metal

T_{m} = Melting Temperature

M = Molecular Weight

Let’s solve an example;

Find the speed of sound in molten metal when the melting temperature is 24 and the molecular weight is 12.

This implies that;

T_{m} = Melting Temperature = 24

M = Molecular Weight = 12

u_{s} = 16(^{Tm} / M)^{0.5}

u_{s} = 16(^{24} / _{12})^{0.5}

u_{s} = 16(2)^{0.5}

u_{s} = 16(1.414)

u_{s} = 22.627

Therefore, the **speed of sound in molten metal **is **22.627 m/s.**
