Estimating fraction of heat injected in latent form (steam-drive)
Input(s)
\(C_{w}\): Specific Heat of Water (BTU/lbm F)
\(T_{i}\): Injection Temperature \(\left({ }^{\circ} \mathrm{F}\right)\)
\(T_{a}\): Ambient Temperature \(\left({ }^{\circ} \mathrm{F}\right)\)
\(f_{\text {sdh }}\): Steam Quality (fraction)
\(L_{h c}\): Latent Heat of Condensation (BTU/lbm)
Output(s)
\(f_{h v}\): Fraction of Heat Injected in Latent Form (fraction)
Formula(s)
\[
\mathrm{f}_{\mathrm{hv}}=\left(1+\left(\left(\mathrm{C}_{\mathrm{w}}\right) * \frac{\mathrm{T}_{\mathrm{i}}-\mathrm{T}_{\mathrm{a}}}{\mathrm{f}_{\mathrm{sdh}} * \mathrm{~L}_{\mathrm{hc}}}\right)\right)^{-1}
\]
