Thermal Conductivity Calculator

Formula

To calculate the Heat Flux (q):

\[ q = - n \frac{\Delta T}{\Delta x} \]

Where:

\(q\) is the Heat Flux (W/m²)
\(n\) is the Thermal Conductivity (W/(m·K))
\(\Delta T\) is the Temperature Difference (K)
\(\Delta x\) is the Distance (m)

What is Thermal Conductivity?

Thermal conductivity refers to the property of a material that determines its ability to conduct heat. It measures how efficiently heat can flow through a substance when there is a temperature difference between two points. In simpler terms, thermal conductivity is a measure of how well a material can transfer heat. It quantifies the rate at which heat energy is conducted through a material. The ability of a substance to conduct heat is crucial in various applications and industries.

Example Calculation

Let's assume the following values:

Thermal Conductivity (\(n\)) = 200 W/(m·K)
Temperature Difference (\(\Delta T\)) = 100 K
Distance (\(\Delta x\)) = 0.01 m

Using the formula:

\[ q = - 200 \frac{100}{0.01} = - 200 \times 10000 = -2000000 \text{ W/m²} \]

The Heat Flux is -2000000 W/m².
