# Fractional flow of water in hot floods dependent on temperature and saturation in hot water flood

## Input(s)

\(M(S, T)\): Mobility Ratio of the Co-flowing Fluids (dimensionless)

## Output(s)

\(f_{w(S, T)}\): Fractional Flow (dimensionless)

## Formula(s)

\[
\mathrm{f}_{\mathrm{w}(\mathrm{S}, \mathrm{T})}=\frac{1}{1+(\mathrm{M}(\mathrm{S}, \mathrm{T}))^{-1}}
\]
