The linear coefficient of thermal expansion for steel varies depending on the specific type of steel and its composition. However, a commonly used average value for the linear coefficient of thermal expansion for carbon steel is approximately 12 x 10^-6 per degree Celsius (12 µm/m·°C).
To calculate the thermal expansion of steel at a specific temperature, you can use the formula:
ΔL = α * L0 * ΔT
Where:
- ΔL is the change in length due to thermal expansion.
- α is the linear coefficient of thermal expansion (12 x 10^-6 per °C for carbon steel).
- L0 is the original length of the steel.
- ΔT is the change in temperature in degrees Celsius.
If you want to calculate the thermal expansion of a specific piece of steel at 100 degrees Celsius, you would use this formula with the given coefficient of thermal expansion. Keep in mind that this is an average value, and the actual coefficient may vary depending on the type of steel. Make sure to use the appropriate coefficient for the specific steel you are working with if it is available.
To calculate the radial expansion in a steel ring when the temperature changes, you can use the formula for thermal expansion. The linear coefficient of thermal expansion for steel, as mentioned earlier, is approximately 12 x 10^-6 per degree Celsius (12 µm/m·°C).
Given:
- Initial diameter (D0) = 100 mm
- Change in temperature (ΔT) = 150°C – 30°C = 120°C
- Linear coefficient of thermal expansion (α) = 12 x 10^-6 per °C
First, calculate the change in diameter (ΔD) due to thermal expansion using the formula:
ΔD = α * D0 * ΔT
Where:
- ΔD is the change in diameter.
- α is the linear coefficient of thermal expansion (12 x 10^-6 per °C for steel).
- D0 is the original diameter (100 mm).
- ΔT is the change in temperature (120°C).
Now, plug in the values:
ΔD = 12 x 10^-6 * 100 mm * 120°C
ΔD = 0.144 mm
So, the radial expansion in the steel ring will be approximately 0.144 mm when the temperature changes from 30°C to 150°C.
