Formula Used in “Thermal Resistance Calculator”
The fundamental formula used in our Thermal Resistance Calculator is based on Fourier’s law of heat conduction. The standard formula is expressed as:
R = frac{L}{k cdot A}
Where:
- R = Thermal resistance (°C/W)
- L = Thickness of the material (m)
- k = Thermal conductivity of the material (W/m·°C)
- A = Surface area through which heat is being transferred (m²)
Step-by-Step Breakdown of the Formula
- Identify the Thickness (L): Measure the thickness of the material through which heat will be conducted. This value should be in meters.
- Determine the Thermal Conductivity (k): Find the thermal conductivity of the material, which indicates how well it conducts heat. This value should be in W/m·°C.
- Calculate the Surface Area (A): Measure or calculate the surface area over which heat is being transferred, in square meters (m²).
- Apply the formula: Use the values gathered from the previous steps to compute the thermal resistance (R) using the formula R = L / (k · A).
Example Calculation
Let’s work through a practical example of using the thermal resistance formula. Suppose we have the following parameters for a wall made of insulation material:
| Parameter | Value | Unit |
|---|---|---|
| Thickness (L) | 0.1 | m |
| Thermal Conductivity (k) | 0.04 | W/m·°C |
| Surface Area (A) | 10 | m² |
Now, we can plug these values into the thermal resistance formula:
R = frac{0.1}{0.04 cdot 10} = frac{0.1}{0.4} = 0.25 , °C/W
Thus, the thermal resistance of the wall is 0.25 °C/W. This indicates that for every watt of heat transferred through this wall, the temperature difference across it will be 0.25 °C.
