Energy emitted from the surface of a black body
Input(s)
S: Stephan-Boltzmann Constant \(\left(\mathrm{lb} /\left(\mathrm{hr}^{3} \mathrm{R}^{4}\right)\right)\)
T: Temperature (R) A: Area \(\left(\mathrm{ft}^{2}\right)\)
Output(s)
\(\left(\boldsymbol{q}_{\boldsymbol{b}}\right)^{\boldsymbol{e}}\): Emitted Heat Flux \(\left(\mathrm{Btu} / \mathrm{h} \mathrm{ft}^{2}\right)\)
Formula(s)
\[
\left(\mathrm{q}_{\mathrm{b}}\right)^{\mathrm{e}}=\rho *\left(\mathrm{~T}^{4}\right)
\]
