Estimating heat injection rate (steam-drive)

Input(s)

$w_{i}$: Boiler Feed Water Rate $(\mathrm{B} / \mathrm{d})$

$C_{w}$: Specific Heat Capacity of Water (BTU/lbm F)

$T_{i}$: Injection Temperature $\left({ }^{\circ} \mathrm{F}\right)$

$T_{a}$: Ambient Temperature $\left({ }^{\circ} \mathrm{F}\right)$

$f_{s d h}$: Steam Quality (fraction)

$L_{h c}$: Latent Heat of Condensation (BTU/lbm)

Output(s)

$Q_{i}$: Heat Injection Rate (BTU/d)

Formula(s)

$$ \mathrm{Q}_{\mathrm{i}}=\mathrm{w}_{\mathrm{i}} * 62.4 * 5.615 *\left(\mathrm{C}_{\mathrm{w}} *\left(\mathrm{~T}_{\mathrm{i}}-\mathrm{T}_{\mathrm{a}}\right)+\mathrm{f}_{\mathrm{sdh}} * \mathrm{~L}_{\mathrm{hc}}\right) $$
