### How Do You Calculate The Coefficient Of Thermal Expansion?

How do you calculate the coefficient of thermal expansion? The dependence of thermal expansion on temperature, substance, and length is summarized in the equation ΔL = αLΔT,where ΔL is the change in length L, ΔT is the change in temperature, and α is the coefficient of linear expansion, which varies slightly with temperature.

## How do you calculate CTE?

• Verify The Result.
• Calculate the Sensitivity Coefficient (Optional)
• ## What is thermal coefficients of expansion?

For isotropic materials, the area and volumetric thermal expansion coefficient are, respectively, approximately twice and three times larger than the linear thermal expansion coefficient. Mathematical definitions of these coefficients are defined below for solids, liquids, and gases.

## What is thermal expansion coefficient for steel?

Like most materials, steel expands when the surrounding temperature increases. Multiply the temperature change by 7.2 x 10-6, which is the expansion coefficient for steel. Continuing the example, you would multiply 0.0000072 by 5 to get 0.000036.

## How do you calculate coefficient of volume expansion?

The equation for the volume expansion is as follows: ΔV = Vo β ΔT, where the change in volume (ΔV) is equal to the initial volume (Vo) multiplied by the coefficient of volume expansion, β, and by the temperature increase.
