Wilson gives the K-factor as

\[ \ln K_i = \ln\left(\frac{p_{c,i}}{p}\right)+5.373(1+\omega_i)\left(1-\frac{T_{c,i}}{T}\right) \]

From Rachford-Rice:

\[ \sum_i \frac{x_i(K_i-1)}{1 - \beta + \beta K_i} = 0 \]

When $T$ is known for $\beta=0$, $p $can be obtained from \f[ -1+\sum_i K_ix_i=0, \f] or \f[ p = \sum_i x_ip_{c,i}\exp(5.373(1+\omega_i)(1-T_{c,i}/T). \f] Or when $@_fakenlT $ is known for $\beta=1 $, $p
