Estimating volume of steam injection (steam-drive)

Input(s)

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

$T_{s b}$: Temperature of Steam at Boiler Outlet $\left({ }^{\circ} \mathrm{F}\right)$

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

$f_{s b}$: Fraction of Steam at Boiler Outlet (fraction)

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

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

$f_{s d h}$: Fraction of Steam Down Hole (fraction)

$L_{v d h}$: Latent Heat of Vaporization Down Hole (BTU/lbm)

$L_{v b}$: Latent Heat of Vaporization at Boiler Outlet (BTU/lbm)

Output(s)
