Boltzmann law formula

WebSep 12, 2024 · Quantitatively, Stefan’s law expresses this relation as P ( T) = σ A T 4 where A is the surface area of a blackbody, T is its temperature (in kelvins), and σ is the Stefan–Boltzmann constant, σ = 5.670 × 10 − 8 W / ( m 2 ⋅ K 4). Stefan’s law enables us to estimate how much energy a star is radiating by remotely measuring its temperature.

WebThe Stefan-Boltzmann formula for emission of heat from a hot body into space is well-known. This law presumes emissivity of unity (i.e., a blackbody). Formulae for cooling of a blackbody given in Section 2.2.3.2 can be adjusted for lower emissivity, but the findings are little affected: cooling by radiation is very fast. WebRadiate energy = (Emissivity) * (Stefan-Boltzmann constant) * (Temperature)4 * (Area) The equation is: P = є σ T 4 A P: Radiate energy σ: The Stefan-Boltzmann Constant T: absolute temperature in Kelvin є: Emissivity of the material.
