Combined radiation and convection

Input(s)

$\boldsymbol{A}_{i}$: Area $\left(\mathrm{ft}^{2}\right)$

$\sigma$: Stephen Boltzmann Constant $\left(\mathrm{lb} / \mathrm{h}^{3} \mathrm{R}^{4}\right)$

$\boldsymbol{e}_{i}$: Emissivity (fraction)

$T_{i}$: Maximum Air Temperature at the Water Surface (R)

Output(s)

Q: Heat Transfer Rate $(\mathrm{Btu} / \mathrm{s})$

Formula(s)

$$ Q=\sigma * A_{i} * e_{i} * T_{i}^{4} $$
