Enter the thermal conductivity, the specific heat, and the density into the Thermal Diffusivity Calculator. The calculator will evaluate the Thermal Diffusivity.

## Thermal Diffusivity Formula

The following formula is used to calculate the Thermal Diffusivity.

TD = k / (Cp*d)

Variables:

• TD is the Thermal Diffusivity ( )
• k is the thermal conductivity
• Cp is the specific heat
• d is the density

## How to Calculate Thermal Diffusivity?

The following steps outline how to calculate the Thermal Diffusivity.

1. First, determine the thermal conductivity.
2. Next, determine the specific heat.
3. Next, determine the density.
4. Next, gather the formula from above = TD = k / (Cp*d).
5. Finally, calculate the Thermal Diffusivity.
6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

thermal conductivity = 5

specific heat = 10

density = 90

TD = k / (Cp*d) =  ?
