The expression W = ε σT4 is called
The expression W = ε σT4 is called
Right Answer is:
Fourier equation
SOLUTION
The Stefan–Boltzmann law, also known as Stefan’s law, states that the total energy radiated per unit surface area of a black body in unit time (known variously as the black-body irradiance, energy-flux density, radiant flux, or the emissive power), is directly proportional to the fourth power of the black body’s thermodynamic temperature T (also called absolute temperature).
The expression W = ε σT4 is called Stefan-Boltzmann equation
W = ε σT4
where
W = Radiate Energy
ε = emissivity
σ = Stefan constant
T = Temperature
