Minimum air flux required for advance of fire front - Nelson and McNiel

Input(s)

$a_{r}$: Air Required to Burn Unit Volume of Reservoir (MSCF/ $\mathrm{ft}^{3}$ )

$E_{O 2}$: Oxygen Consumption Efficiency (fraction)

Output(s)

$u_{\text {min }}$: Minimum Air Flux $\left(\mathrm{SCF} / \mathrm{ft}^{2} \mathrm{~d}\right)$

Formula(s)

$$ \mathrm{u}_{\min }=\frac{0.125 * \mathrm{a}_{\mathrm{r}}}{\mathrm{E}_{\mathrm{O} 2}} $$
