Dimensionless ratio of effective volumetric heat capacity of injected steam to that of the steam zone

Input(s)

$\rho_{w}$: Density of Water $(\mathrm{g} / \mathrm{cc})$

$C_{w}$: Specific Heat of Water $(\mathrm{BTU} / \mathrm{K} \mathrm{mol} \mathrm{psi})$

dT: Temperature Differential $(\mathrm{K})$

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

$L_{v}$: Latent Heat of Vaporization (BTU/lbm)

$M_{r}$: Volumetric Heat Capacity of the Reservoir (BTU/ $\mathrm{ft}^{3} \mathrm{~K}$ )

Output(s)

$F_{d h}$: Dimensionless Ratio of Effective Volumetric Heat Capacity of injected Steam to that of the Steam Zone (dimensionless)
