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