Scientific Basis of the Emissivity Calculator
The Emissivity Calculator is grounded in the Stefan-Boltzmann Law, which states that the power radiated by a black body is proportional to the fourth power of its absolute temperature. The formula is:
P = εσT⁴
Where:
- P is the radiant power per unit area (W/m²).
- ε is the emissivity of the surface (dimensionless, 0 to 1).
- σ is the Stefan-Boltzmann constant (5.670367 × 10⁻⁸ W/m²·K⁴).
- T is the absolute temperature in Kelvin (K = °C + 273.15).
This formula, validated through extensive peer-reviewed research, ensures the calculator delivers accurate results for real-world applications.
